2Co + 3HgCl2 ==> 2CoCl3 + 3Hg
mols Co = grams/atomic mass
Using the coefficients in the balanced equation, convert mols Co to mols Hg.
Now convert mols Hg to grams; i.e., g = mols x atomic mass = ?
What is the mass of mercury that can be prepared from 2.00 g of cobalt metal?
Co(s)+HgCl2(aq)→CoCl3(aq)+Hg(l)
