how many cubic cm hydrogen chloride gas at s.t.p would be required to precipitate all the silver ions from 32 cm of 0.08 M silver nitric solution?

Answer 1

You really should be more careful in writing these problems. cc or cm^3 and not cm. silver nitrate solution and not silver nitric, etc.

HCl + AgNO3 ==> AgCl + HNO3
mols AgNO3 = M x L = ?
mols HCl = mols AgNO3
Convert mols HCl to volume using PV = nRT. The answer will be in L, convert to mL or cc.
mols HCl = mols AgNO3
