Question

Equal volumes of sodium chloride solution and sodium hydroxide solution (each having concentration of 0.25 mol/dm3) are mixed. Calculate the concentrations of
sodium ions,
chloride ions,
hydroxide ions.​

Answer 1

A concentration expressed on an m/m basis is equal to the number of grams of solute per gram of solution; a concentration on an m/v basis is the number of grams of solute per milliliter of solution. Each measurement can be expressed as a percentage by multiplying the ratio by 100; the result is reported as percent m/m or percent m/v
