Hydrochloric acid reacts with lithium hydroxide in a 1:1 equation. A 24.0 cm3 sample of the acid, at 0.150 mol dm−30.150\,\mathrm{mol\,dm^{-3}}0.150moldm−3, reacts exactly with 18.0 cm3 of lithium hydroxide solution.
What is the concentration of the lithium hydroxide solution?
0.113 mol dm−30.113\,\mathrm{mol\,dm^{-3}}0.113moldm−3
0.200 mol dm−30.200\,\mathrm{mol\,dm^{-3}}0.200moldm−3
