Does Calcium accounts for around 27% ?

Pedro J Romero

Calcium accounts for by 75.5% in dydrate calcium chloride mass

Thanks Professor Pedro J Romero, please correct me if I am wrong:

Ca = 40.08

Cl2 = (35.45) x 2 = 70.9

2H2O = (18.02) x 2 = 36.04

40.08 + 70.90 + 36.04 = 147.02 g/mol

so (40.8 / 147.02) X 100= 27.7 % ??

Is that correct ?
