How Many Hydrogen Atomes Are In 150.0g Of Glucose

How Many HydrogenAtoms Are in 150.0g of Glucose?

Glucose, a simple sugar essential for energy production in living organisms, has the chemical formula C₆H₁₂O₆. This means each molecule of glucose contains 12 hydrogen atoms. To determine the total number of hydrogen atoms in 150.0 grams of glucose, we must follow a series of calculations rooted in chemistry principles. This process involves converting mass to moles, accounting for molecular composition, and scaling up to atomic-level quantities. Below, we break down the steps and scientific reasoning behind this calculation.

Step 1: Determine the Molar Mass of Glucose

The first step is to calculate the molar mass of glucose (C₆H₁₂O₆). The molar mass is the sum of the atomic masses of all atoms in a molecule:

• Carbon (C): 6 atoms × 12.01 g/mol = 72.06 g/mol
• Hydrogen (H): 12 atoms × 1.008 g/mol = 12.096 g/mol
• Oxygen (O): 6 atoms × 16.00 g/mol = 96.00 g/mol

Total molar mass of glucose = 72.06 + 12.096 + 96.00 = 180.156 g/mol

This value is critical because it bridges the gap between the macroscopic mass of glucose and the microscopic number of molecules.

Step 2: Convert Grams of Glucose to Moles

Using the molar mass, we convert the given mass of glucose (150.0 g) into moles:
$ \text{Moles of glucose} = \frac{\text{Mass of glucose}}{\text{Molar mass of glucose}} = \frac{150.0\ \text{g}}{180.156\ \text{g/mol}} \approx 0.8326\ \text{mol} $

This calculation tells us that 150.But 0 grams of glucose corresponds to approximately 0. 8326 moles of glucose molecules.

Step 3: Calculate Moles of Hydrogen Atoms

Each glucose molecule contains 12 hydrogen atoms. To find the total moles of hydrogen atoms:
$ \text{Moles of H atoms} = \text{Moles of glucose} \times 12 = 0.8326\ \text{mol} \times 12 = 9.9912\ \text{mol} $

Rounded to four significant figures (matching the precision of the given mass), this becomes 9.991 moles of hydrogen atoms.

Step 4: Convert Moles of Hydrogen to Number of Atoms

Finally, we use Avogadro’s number

Step 4: ConvertMoles of Hydrogen to Number of Atoms
To find the actual number of hydrogen atoms, multiply the moles of hydrogen by Avogadro’s number (6.022 × 10²³ atoms/mol):
$ \text{Number of H atoms} = 9.991\ \text{mol} \times 6.022 \times 10^{23}\ \text{atoms/mol} \approx 6.017 \times 10^{24}\ \text{atoms} $

This gives a staggering number of hydrogen atoms in 150.0 grams of glucose, illustrating the vast scale of atomic quantities in macroscopic samples That's the part that actually makes a difference..

Conclusion

Calculating the number of hydrogen atoms in a given mass of glucose demonstrates the interplay between macroscopic measurements and atomic-scale reality. By using molar mass, Avogadro’s number, and the molecular formula of glucose, we bridge the gap between grams and individual atoms. Such calculations are fundamental in fields like chemistry, biology, and materials science, where understanding the composition of substances at the atomic level is crucial. Whether for energy production, pharmaceuticals, or industrial processes, these principles allow scientists to quantify and manipulate matter with precision, highlighting the elegance and utility of chemical stoichiometry.

The final answer is approximately 6.Consider this: 017 × 10²⁴ hydrogen atoms in 150. 0 grams of glucose And that's really what it comes down to..

Step 5: Verifying Significant Figures and Units

Before we close the calculation, it’s worth double‑checking that the result respects the precision of the original data.

Because the limiting datum is the mass (4 sf), the final answer should be reported to four significant figures:

[ N_{\text{H}} = 6.017 \times 10^{24}\ \text{atoms} ]

The unit “atoms” is explicit, and no further conversion is required.

Common Pitfalls to Avoid

1. Skipping the atomic‑count step – It’s easy to stop after finding moles of hydrogen. Remember that a mole is a count of entities, not a mass; you must still multiply by Avogadro’s number to obtain the actual number of atoms.
2. Mismatching significant figures – Carrying too many digits through each intermediate step can give a false sense of precision. Keep track of the limiting measurement (here, the 150.0 g mass).
3. Confusing molecular vs. atomic masses – The molar mass of glucose already incorporates the masses of all constituent atoms. Do not add the atomic masses again when you later multiply by the number of hydrogen atoms per molecule.

Why This Matters in Real‑World Contexts

• Metabolic calculations – Knowing the exact number of hydrogen atoms (or, more generally, the number of atoms of any element) in a substrate like glucose helps biochemists estimate how many reducing equivalents (e.g., NADH) can be generated during glycolysis and the citric‑acid cycle.
• Stoichiometric design of reactors – In industrial fermentation, engineers must balance feedstock inputs with product outputs on a molecular basis. Translating grams of feedstock into atom counts ensures that mass balances close correctly.
• Radiation dosimetry – The number of hydrogen atoms influences the hydrogen‑content of a material, which in turn affects how it interacts with neutron radiation. Accurate atom counts are therefore essential for shielding calculations.

Final Take‑Away

By systematically applying three core concepts—molar mass, the mole‑to‑atom conversion, and significant‑figure discipline—we transformed a macroscopic sample of glucose (150.0 g) into a microscopic tally of hydrogen atoms:

[ \boxed{6.017 \times 10^{24}\ \text{hydrogen atoms}} ]

Whether you are a student mastering introductory chemistry or a professional designing a bioprocess, the same logical steps will guide you from grams to atoms, from bulk matter to the fundamental building blocks of chemistry.
