In the first case, there are a variety of ways to do that, but the best ones involve using a gas chromatograph or other instrument.
For the other two cases, one of the compounds is very soluble in water, but the second isn't. So, you could take a known weight of the solid, mix it with water, collect what remains insoluble and weigh it.

in the second one, no because there is no Hg in CuSO4+4H2O
in the third, no because there is no Calcium in KClO3
