Question

A compound is made up of various elements totaling 110 ounces. If the total amount of lead in the compound weighs 2 ounces, what percent of the compound is made up of lead? If necessary, round your answer to the nearest hundredth of a percent.

Answer 1

To find the answer we can first put the amount of lead in the total compound:

2/110

We can then proceed to find the percentage:

2/110 x 100%
=0.01818181...×100%
= 1.81%(correct to nearest hundredth)

Therefore the answer is 1.81%.

Hope it helps!
