If the crucible originally weighs 3.715 g and 2.000 g of hydrate are added to it, what is the weight of the water that is lost if the final weight of the crucible and anhydrous salt is 5.384? Do not include units and assume three decimal places for all numbers. Remember to include the zero before the decimal if the number is less than one.
