Web3 mei 2016 · Explanation: Clearly there is a 1:1 equivalence, and as a first step we calculate the number of moles of hydrochloric acid: 45.0 ×10−3 ⋅ L ×0.400 ⋅ mol ⋅ L−1 = 1.80 × 10−2 ⋅ mol hydrochloric acid. We find an equivalent molar quantity of sodium hydroxide: 1.80× 10−2 ⋅ mol 0.500 ⋅ mol ⋅ L−1 ×103 ⋅ mL ⋅ L−1 = 36.0 ⋅ mL. sds tool
