How many grams of PbCO3 will dissolve when exactly 5.0 L of 1.25 M H is added to 6.0 g of PbCO3?

When the equation is PbCO3(s) + 2H(+)(aq) = Pb(2+)(aq) + H2O(l) + CO2(g)

Is this anything more than a stoichiometry problem? I don't think so.
Here is a set of directions for working stoichiometry problems. M x L = moles. Convert moles H^+ to moles Pb^2+ and convert to grams PbCO3.
