Calculate mass/volume percentage of 20% solution by mass of sulphuric acid
Open in App
Solution
Here in the problem denisty is missing let density = 1.02g/ml 20% sulphuric acid suggests that 20 ml of sulphuric acid in 100 ml of solution volume of solute = 20ml volume of solution = 100 ml volume of solvent = 100-20 = 80 ml Density = mass/volume mass of sulphuric acid = density* volume = 1.02 * 20 =20.4 g volume of solution = volume of solvent = 80 ml Mass by volume % = ( mass of solute/volume of solution ) *100 = 20.4 /80 *100 = 25.5%
