We have that the the percent by mass of water present is mathematically given as
x=20.9%
Question Parameters:
the percent by mass of water present in 1.0 mole of caso4 times 2h20
Generally the equation for the Molecular mass of Caso4 is mathematically given as
40.1 grams/mole + 32.1 grams/mole +16 x 4+ water 18.0 grams/mole x 2 = 172.2 grams/mole
Since, water's Mass number is 32
X=36.0/ 172.2
x= 0.209059
x=20.9%
