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
1 answer:
Answer:
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
