Define what is the value of x in the formula for the hydrate

Reference no: EM13267903

When 0.234 g of the hydrate Cr2(SO4)3•xH2O is heated, 0.128 grams of anhydrous Cr2(SO4)3 remains. What is the value of x in the formula for the hydrate? (hint: remember that x represents the ratio of moles of H2O to moles of hydrate compound, and that moles of hydrate compound equals the moles of anhydrous compound)
