Answer to Question #187317 in Chemistry for Lily

Question

What is the mass (grams) of 4.62x10²⁴ in molecules of glucose (C6H12O6)

Answer 1

Solution:

One mole of any substance contains 6.022×10²³ atoms/molecules.

Hence,

n(C₆H₁₂O₆) = (4.62×10²⁴ molecules of C₆H₁₂O₆) × (1 mol / 6.022×10²³ molecules) = 7.672 mol C₆H₁₂O₆

The molar mass of C₆H₁₂O₆ is 180.156 g/mol.

Hence,

(7.672 mol C₆H₁₂O₆) × (180.156 g C₆H₁₂O₆ / 1 mol C₆H₁₂O₆) = 1382.15 g C₆H₁₂O₆

Mass of C₆H₁₂O₆ = 1382.15 g

Answer: 1382.15 grams of glucose (C₆H₁₂O₆) are in 4.62×10²⁴ molecules of glucose.
