In a chemical compound there are three parts zinc for every 16 parts copper by mass. A piece of the compound contains 320 g of copper. Write and solve an equation to determine the amount of zinc in the chemical compound.
Total mass contains 320g copper. How many parts of 16g copper are there of the total mass of 320g copper? 320/16 = 20. There are 20 portions of 16g copper.
(320/16) * 3 = 60g
There are 60g of zinc in the compound.
