Question

In 24.954 g CuSO4.5H20 the number of SO4 2- ions is? Molecular mass is 249.95

Answer 1

Answer:

The concn in blood, muscle, and most of the viscera range from 0.85 to 1.90 ppm. Values for plasma lie in the narrow range of 1.16 to 1.42 ppm

Answer 2

Answer:

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)
