Feliz [49]

Answer:

CuSO4.5H2O

Explanation:

Recall that;

mass of anhydrous salt/ molar mass of anhydrous salt  = mass of hydrated salt/molar mass of hydrated salt

mass of anhydrous salt =  27.38 g

mass of hydrated salt = 42.75 g

molar mass of anhydrous salt = 160 g/mol

molar mass of hydrated salt = 160 + 18x

27.38 g/160 g/mol = 42.75 g/160 + 18x

27.38 (160 + 18x) =160 * 42.75

4380.8 + 492.84x = 6840

492.84x = 6840 - 4380.8

492.84x = 2459.2

x = 2459.2/492.84

x = 5

Hence the formula of the hydrate is; CuSO4.5H2O
