If a smartie contains 9.08 x 1022 atoms of hydrogen from glucose C6H12O2, what is the mass of glucose in the smartie?

grams glucose (C₆H₁₂O₆) * in smartie = 2.26 grams

Explanation:

*Formula for glucose is = > C₆H₁₂O₆ (corrected for problem text) and has formula weight of 180.156 g/mole.

The total number of hydrogen atoms in 1 mole of glucose = 12moles (6.02 x 10²³atoms H/mole) = 7.224 x 10²⁴ atoms H

Fraction of mole containing 9.08 x 10²² atoms H = (9.08 x 10²²atoms H/7.224 x 10²⁴atoms H/mole glucose) = 0.0126 of mole of glucose

Formula Weight of 1 mole glucose = 180 grams/mole

∴mass glucose containing 9.08 x 10²² H atoms = 0.0126mole x 180 g/mole = 2.26 grams glucose in smartie.
