A sample of Magnesium Oxide was found to be contaminated with the sodium chloride. Magnesium oxide is not very soluble in water but can be dissolved in an excess of the standardisted HClIn order to determine the purity of the magnesium oxide, 3.86g of the sample was dissolved in 500ml of Hcl and then 50ml of the resulting solution was titrated against the NaOH solution of known concentration. The average titration volume was found to be 10.4ml.Calculate the percentage of magnesium oxide in the concentration sample.
