A mole is 6.02*10^23 molecules.
The molar weight of a compound is the sum of the atomic weights
Copper sulfate is CuSO4
Atomic weights
Cu = 63.5
S = 32
O = 16
CuSO4 = 63.5 + 32 + 16*4 = 159.5
2.7*10^24 molecules * 159.5 g CuSO4/mole * 1 mole/6.02*10^23 molecules = (2.7 * 159.5 * 10)/6.02 = 715.37 grams
