Question

calculate the molecular mass of CuSO4.5H20
( given atomic mass of Cu = 63.5, H=1, O = 16 ,C= 12, N= 14, Mg =24 and S=32)

Answer 1

Answer:

Explanation:

Molar mass of CuSO4.5H2O=249.5

Answer 2

Molar mass of CuSO4.5H2O = 249.685 g/mol

Convert grams CuSO4.5H2O to moles  or  moles CuSO4.5H2O to grams

Molecular weight calculation:

63.546 + 32.065 + 15.9994*4 + 5*(1.00794*2 + 15.9994)
