Data is collected is iron (II) sulfate hydrate. Mass of test tube is 27.2904g, Mass of test tube and hydrate is 28.5633g, Mass of test tube and anhydrous residue after heating is 27.9858g
I have to: calculate the mass percent of water in the hydrate, calculate the moles of water in the hydrate sample that were driven off by heating, and calculate the mole ratio of water to salt in the hydrate. all needed to write the correct formula of the hydrate.
I know how to do the basic mole to mole rations, and conversions
my question is: how do i determine the mass of water (in g's) that was driven off? do i subtracted the mass of the test tube with the anhydrous residue from the mass of the test tube with the hydrate?
