Question

The complete question is On average, earth's crust contains about 8.1% aluminum by mass. If a standard 12-ounce soft drinks can contains approximately 15g of aluminum, how many cans could be made from one ton of the earth's crust? Solution with explanation please. TIA!

Answer 1

1 ton=1.016960×10⁶g approx. 1 tonne (metric ton)=10⁶g.

0.081 of this is either 82,373.76g or 81,000g depending on whether imperial or metric measurement is intended. The number of cans is therefore 82373.76/15=5491 or 81000/15=5400.
