Question

How many moles in 35 g of CuSO4

Answer 1

Answer: 0.219 moles of CuSO4

Explanation:

1) Calculate the molar mass of the compound:

Cu: 63.55 g/mol
S: 32.06 g/mol
O4: 16.00(4) = 64 g/mol

CuSO4 = 159.61

2) Divide the molar mass of the molecule:

To go from grams to moles, you need to divide the mass of the compound by its molar mass:

35g CuSO4 (
`(1 mol)/(159.61 g/mol)`) = 0.219 moles of CuSO4
