The chemical equation for the reaction is: NaOH+ HNO3 = NaNO3 + H2O According to the equation the number of moles of the acid is equal to the number of moles of the base. n(NaOH)= n(HNO3) n(mol)= C(M)∙V(L) C(NaOH)∙V(NaOH)= C(HNO3)∙V(HNO3) 2.0M∙ 2.5L = 5.0M∙V(HNO3) V(HNO3)=(2.0∙2.5)/5.0 = 5.0/5.0 = 1 L Answer: V(HNO3)=1 L
