Q2 of 30 Page 34

A solution contains 40g of common salt in 320g of water. Calculate the concentration in terms of mass by mass %.

Mass of solute (common salt) = 40g

Mass of solvent = 320g


Total mass of solution = mass of solute + mass of solvent


Total mass of solution = 40g + 320g


Total mass of solution = 360g


To calculate concentration in terms of mass by mass percentage of the solution, apply the formula:




Percentage by volume = 11%

A compound 'X' is constituent of baking powder. It is used as an antacid. When 'X' is heated, it gives out a 'Y' which when passed through lime water turns it milky, and salt 'Z' is formed which is the main constituent of washing powder. Identify X Y and Z. Write balanced chemical equations for the reactions involved.
