64.60 g of water is how many moles of water H2O

3.586 mol of H2O (correct to 4 sig figs)

Explanation:

Known: 64.60 g water (a.k.a. H2O)

1 mol of H2O = 18.015g

How did I get that mass? Looking at the periodic table and adding atomic mass of 2 hydrogens + 1 oxygen ( 2(1.008) +15.999) = 18.015g

How many of mol of H2O will form?

Solving for the  unknown:

64.60g • (1 mol H2O / 18.015g H2O) = 3.58590 mol H2O

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
