ANSWER
a)
➡️Potassium sulphate(K2SO4)=174.259
➡️Potassium(k) =39.09=>2×39.09
=>78.18%
➡️Potassium %age=78.18/174.259×100
=>44.86%
➡️Sulphate(SO4)=96.06
➡️Sulphate %age=96.06/174.259×100
=>55.12%
b)
➡️Sodium sulphate(Na2SO4)=142.04
➡️Sodium(Na)=23=>2×23=>46
➡️Sodium %age=46/142.04×100
=>32.38%
➡️Sulphate(SO4)=96.06
➡️Sulphate %age=96.06/142.04×100
=>67.62%
C)
➡️Calcium carbonate(CaCO3)=100.089
➡️Calcium(Ca)=40.07
➡️Calcium %age=40.07/100.089×100
=>40.03%
➡️Carbonate(CO3)=60.008
➡️Carbonate %age=60.008/100.089×100
=>59.95%
