Question

Calculate the Molar Mass of CuSO4

Answer 1

The molar mass of CuSO4 is 159.62 g/mol.

Step-by-step explanation:

The molar mass of CuSO4 can be calculated by adding up the atomic masses of all the elements in the compound:

Molar mass of Cu = 63.55 g/mol

Molar mass of S = 32.07 g/mol

Molar mass of O = 16.00 g/mol

Molar mass of 4 O = 4 x 16.00 g/mol = 64.00 g/mol

Adding up all the atomic masses:

Molar mass of CuSO4 = 63.55 g/mol + 32.07 g/mol + 64.00 g/mol = 159.62 g/mol

Answer 2

The molar mass of a molecule corresponds to the sum of the atomic weights of each element multiplied by the number of atoms of the respective element. The atomic weights can be found in the periodic table. For each element the atomic weight is:

Cu=63.546u

S= 32.065 u

O4= 15.999u

The molar mass of the molecule will be:

`MolarMassCuSO_4=1*63.546u+1*32.065u+4*15.999u`
`MolarMassCuSO_4=63.546u+32.065u+63.996u`
`MolarMassCuSO_4=159.607g/mol`

Answer: The molar mass of CuSO4 is 159.607g/mol
