MrMuchimi

Answer:

5400 cans

Explanation:

First we convert the total weight, 1 ton, to grams:

1ton=1x10^{6}g

Now we need to know the mass of aluminum:

m_{Al}=\frac{10^{6}*8.1}{100} =81000g

Now we make the relation between the mass of aluminum in 1 ton of the earth's crust and the mass of aluminum per can:

n=\frac{81000g}{15g/can} =5400cans
