When a solution of sodium lactate, CH3CH (OH) COONA, is mixed with an aqueous copper(II) solution, it is possible to obtain a solid salt of copper(II) lactate as a blue-green hydrate,(CH3CH(OH)COO)2C xH2O. Elemental analysis of the solid tells us that the solid is 22.9% Cu and 26.0% C by mass. Calculate the value for x in the formula for the hydrate?
