The student determines the mass of the Barium sulphate to be 0.3458. The science teacher then calculates the percentage yields achieved by the student to be 86%. a) Use the molar ratios from the balanced chemical equation to determine the mass of potassium sulphate used by the student in this practical exam (experimental mass) b) Given that the percentage yield is 86%, calculate the actual mass of Potassium sulphate((K2504)) dissolved in water by the teachers c) Give a possible reason why the student achieved a yield of less than 100%
