Calculate the normality of Cu2+ in a solution that is made by dissolving 8.77 g of Au(NO 3 ) 3 in enough water to make 175 mL of solution when copper metal is added to the solution.
Calculating percent by mass/volume. Chem Worksheet 15-2. The concentration of a solution can be expressed as a percent – the ratio of solute to solution. This calculation is commonly performed based on the mass of a substance (m/m) or on the volume of substances (v/v).
1 Αυγ 2024 · Mass percent composition is also known as percent by weight. It is abbreviated as w/w%. For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%.
