Determine the mass in grams of 1.6 x 10^-3 mol glucose, C₆H₁₂O₆

Question

1.6 x 10^-3 mol C₆H₁₂O₆ x (----) x (----) = ?

Answer 1

If you are given moles and molecular formula of a substance, you can find mass in grams:

Atomic weight of glucose:

C6 = 72.06

H12 = 12.01

O 6= 96

Total: 180.18g/mol.

1.6x10^-3 mol *180.18g/mol. Mold cancel top to bottom and you have:
