Question

what is the percentage by mass of Nitrogen in calcium sulfate​

Answer 1

ular weight of Calcium Sulfate

Calcium Sulfate molecular weight

Molar mass of CaSO4 = 136.1406 g/mol

Convert grams Calcium Sulfate to moles  or  moles Calcium Sulfate to grams

Molecular weight calculation:

40.078 + 32.065 + 15.9994*4
