A solid hydrate with a mass of 2.125 g was heated to drive off the water. A solid anhydrous residue remained, who’s mass was 1.044 g. Calculate the percent water in the hydrate. If the anhydrous residue has a formula weight of 104 g, how many water molecules are present in each molecule of anhydrous salt?

Take the hydrate mass and divide it with the dry mass
and then make your answer into a percentage thats how you find the percentage of the water the answer you get will be the dry material so just minus that with 100 after its a percentage to find the percentage of water
