If 1.5g of calcium sulfate dihydrate decomposed to a monohydrate what is the theoretical yield of the calcium sulfate monohydrate be?

Answer 1

The theoretical yield is 100%. I assume you want to calculate the mass of the CaSO4.H2O remaining.
CaSO4,2H2O ==> CaSO4.H2O + H2O

mm stands for molar mss
1.5 g x (mm CaSO4.H2O/mm CaSO4.2H2O) = ? g CaSO4.H2O

Answer 2

Thank you
