The mole is 6.02 x 10 23 particles. If a person masses out the correct molar mass in grams for a substance then she would have an entire mole of it. If the molar mass for H2O is 18 g and Mrs. Q had 36 grams of H2O then how many molecules did she have?

1 mole of H2O is 18 grams (2 g H + 16 g Oxygen)

36 / 18 = 2

So 2 moles = 2 * 6.02E23 = 12.04E23 = 1.204E24
