Question 6

During a quality-control check, a technician places 25.0 cm3 of lithium hydroxide solution in a flask. Exact neutralisation requires 15.0 cm3 of 0.300 mol/dm3 nitric acid. The equation is LiOH+HNO3→LiNO3+H2O\text{LiOH} + \text{HNO}_3 \rightarrow \text{LiNO}_3 + \text{H}_2\text{O}LiOH+HNO3​→LiNO3​+H2​O. What is the concentration of the lithium hydroxide solution?
