Answer: g/mol
Explanation:
The gram formula mass of CuSO
4 is 159.60 g/mol
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
:
(

×
63.546 g/mol
) =
63.546 g/mol
S
:
(

32.065 g/mol
) =
32.06 g/mol
O
:
(
4×
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)
