Answer:

The gram formula mass of #"CuSO"_4"# is #"159.60 g/mol"#

Explanation:

Multiply the subscript for each element by its molar mass (atomic mass on periodic table in g/mol). Then add the results. This will give you the molar mass of the compound (mass of 1 mole).

#"Cu":##(1xx"63.546 g/mol")="63.546 g/mol"#

#"S":##(1xx"32.065 g/mol")="32.06 g/mol"#

#"O":##(4xx"15.999 g/mol")="63.996 g/mol"#

#"CuSO"_4":##"63.546 g/mol"+"32.06 g/mol"+"63.996 g/mol"="159.60 g/mol"# (rounded to two decimal places)
