An aqueous solution of nitric acid is standardized by titration with a 0.121 M solution of calcium hydroxide.

If 24.5 mL of base are required to neutralize 15.4 mL of the acid, what is the molarity of the nitric acid solution?

2HNO3 + Ca(OH)2 ==> Ca(NO3)2 + 2H2O
mols Ca(OH)2 = M x L = ?
Convert mols Ca(OH)2 to mols HNO3 using the coefficients in the balanced equation.
M HNO3 = mols HNO3/L HNO3
