What is the percent by mass of water present in 1.0 mole of caso4 times 2h20?

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%

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
