1. You can use Avogadro’s number, 6.022x10^23 atoms/mole, to answer this one.

(3.311x10^24/6.022x10^23) = 5.498 moles of substance

2. H2O has a formula weight approximately equal to 18 grams. Dividing the given amount by the formula weight of water will tell us the number of moles present.

126/18 = 7 moles H2O
