Question

The department of transportation uses a mixture of sand and salt to de-ice roadways in the winter. The mixture contains 8.35 tons of salt and 6.28 tons of sand. What is the mass percent of each component in the mixture?

Answer 1

The mass percent of salt and sand would be 57.07% and 42.93% respectively.

The mass percent can be calculated as:

•   Mass of each component/total mass of all the components x 100

Total mass of all the components = 8.35 + 6.28

                                                          = 14.63 tons

Mass percent of salt = 8.35/14.63 x 100

                                  = 57.07 %

Mass percent of sand = 6.28/14.63 x 100

                                     = 42.93%
