Question

How many moles of aluminum exist in 100.0 g of aluminum?

Answer 1

Step-by-step explanation:

Hi there!

We have,

Molecular mass of an aluminum is 27 g.

According to the mole concept,

Then, 27 g of Al = 1 mole

1 g of Al =
`(1)/(27)` mole

100.0 g of Al =
`(1)/(27)`*100 mole

Therefore, 100.0 g of Al has 3.70 moles.

Hope it helps!
