On average, earth's crust contains about 8.1% aluminum by mass. If a standard 12-ounce soft drink can contains approximately 15.0g of aluminum, how many cans could be made from one ton of the Earth's crust?
4900
1 ton = 2,000 pounds.
2,000 pounds = about 907,185 grams. You can go through the conversion. Repost if you need some help with that.
g Al = 907185*0.081 = ??
15.0 g/can x #cans = 907185*0.081
Solve for #cans.
5400 cans
1000 kg in 1 metric ton
1000 g in 1 kg
times 8.1
divided by 15 grams per can
