Green Gold is made from gold and silver in the ratio 3:1.A green gold bracelet has the mass of 56g

Question

(A)What is the mass of the gold?

(B)Show how to check your answer in part A

Answer 1

So green gold is 3 parts gold and one part silver. We must assume that 3:1 is the mass ratio. So, if the GG has a mass of 56g, 3/4 of that is due to the gold. So the mass of the Gold is 3/4(56) = 42 grams.

To check our answer, we can add the mass of the gold (42 grams) to the mass of the silver (1/4)56 = 14 grams to get the total mass of 14 + 42 = 56 grams!

Bingo!
