How many molecules are there in 8.00 grams of glucose, C6H12O6

molecules C6H12O6 = 2.674 E22 molecules.

Explanation:

from periodic table:

⇒ molecular mass C6H12O6 = ((6) (12.011)) + ((12) (1.008)) + ((6) (15.999))

⇒ Mw C6H12O6 = 180.156 g/mol

⇒ mol C6H12O6 = (8.00 g) (mol/180.156 g) = 0.0444 mol C6H12O6

∴ mol ≡ 6.022 E23 molecules

⇒ molecules C6H12O6 = (0.0444 mol) (6.022 E23 molecules/mol)

⇒ molecules C6H12O6 = 2.674 E22 molecules
