Respuesta :

We have that the the percent by mass of water present  is mathematically given as

x=20.9%

Mass of water

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%
