Question

A group of students collected 125 empty aluminum cans to take to the recycling center. If 21 cans make 1.0 pound of aluminum, how many liters of aluminum (D=2.70g/cm³) are obtained from the cans?

Answer 1

$1 .0pound = 453.592 grams$

Total mass of cans $=\frac{125×453.592}{21}=2699.95grams$

$Volume=\frac{2699.95}{2.70}=999.98cm^3$

$999.98cm^3 = 0.9998 litres$
