If 380. mL of 0.4294 M aqueous CaBr2 and 250. mL of 0.5880 M aqueous SO42- are reacted stoichiometrically according to the equation, how many mol of CaBr2 remained?

Al2(SO4)3(aq) + 3 CaBr2(aq) → 2 AlBr3(aq) + 3 CaSO4(s)
-----------------------------------------

If 270. mL of 0.08089 M aqueous Pb(NO3)2 and 710. mL of 0.05493 M aqueous Na+ are reacted stoichiometrically according to the equation, what mass (g) of Na+ remained?

Pb(NO3)2(aq) + 2 NaI(aq) → PbI2(s) + 2 NaNO3(aq)
---------------------------------------
If 0.0490 mol of solid CaCO3 and 380 mL of 0.135 M aqueous H2SO4 are reacted, what volume (L) of gaseous CO2 measured at 1.1 atm pressure and 301 K is produced.

H2SO4(aq) + CaCO3(s) → CO2(g) + CaSO4(s) + H2O(l)
