Separations part 3

Question

If a sample contained 11.647 g of sand, 0.975 g of sodium chloride and 8.824 g of tin shot, what is

the percentage of each component in the mixture?

Answer 1

Total mass = 11.647 g + 0.975 g + 8.824 g = 21.446 g

Each individual component's percentage will be the mass of the component divided by the total and multiplied by 100.

11.647 g / 21.446 g * 100 = 54.3%

Repeat the process for the other two.
