3.00 g of the hydrate CoCl2.xH2O was heated and after the water was driven off, 1.64 g of CoCl2 remained. (Use these atomic masses: Co = 59 Cl= 35.5 H = 1 O =16 ) You are required to find x by following the steps outlined below.
Find the following:
a. The mass of water driven off
b. The number of moles of H2O driven off
c. The number of moles of CoCl2 formed
d. The number of moles of H2O divide by the number of moles of CoCl2 = x (write as a whole number)
e. The full formula of the hydrate
