When 0.170 g of the hydrate CaCl2•xH2O is heated, 0.128 grams of anhydrous CaCl2 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)
