if 225 mLs of .50 molars of hydrofloric (HF) acid solution is reacted with 25.5 grams of solid zinc what is the most (in grams) aqueous zinc flouride that would be produced? Based on this, how much nonlimiting ractants will be left over?

This is the same kind of problem as the C3H8 + O2 I worked earlier. The only difference is that in reactions involving all gases, L may be used as if they were moles. When grams is used, one must convert to moles by moles = grams/molar mass. Here is a link that you can follow for working simple stoichiometry problems. Just do it twice, once for the Zn and once for the HF.
