what mass of precipitate should result when 0.550L of 0.500 mol/L aluminum nitrate solution is mixed with 0.240L of 1.50mol/L sodium hydroxide solution?

1.17 mol hcl and 2.5 mol naoh react according to the equation hcl + naoh -> nacl + h2o . if the limiting reactant is hcl, determine the amount of excess reactant that remains. answer in units of mol.
