A certain metal alloy is composed of 10% tin, 16% antimony, and 74% lead. If you were to have 500 g of the alloy, how many grams of antimony would be found in this sample?

a. 370g

b. 50g

c. 80g

d. 16g

c. 80 g

Explanation:

metal alloy:

wt% = (mass compound/mass alloy) * 100

for antimony:

⇒ 16% = (g antimony / g alloy) * 100

⇒ 0.16 = g antimony / g alloy

∴ g alloy = 500 g

⇒ (0.16) * (500 g) = g antimony

⇒ g antimony = 80 g
