Q:
# PLEASE HELP! Ordinary brass contains 61.6% copper, 2.9% lead, 0.2% tin, and 35.3% zinc. How many pounds of each metal would be in 160 lb. of brass?

Accepted Solution

A:

There would be 98.56 lbs of copper, 4.64 lbs of lead, 0.32 lbs of tin, and 56.48 lbs of zinc.

61.6% = 0.616; 160(0.616)=98.56

2.9% = 0.029; 160(0.029) = 4.64

0.2% = 0.002; 160(0.002) = 0.32

35.3% = 0.353; 160(0.353) = 56.48

61.6% = 0.616; 160(0.616)=98.56

2.9% = 0.029; 160(0.029) = 4.64

0.2% = 0.002; 160(0.002) = 0.32

35.3% = 0.353; 160(0.353) = 56.48
