# How many moles are there in 54g of Aluminium?

Contents

For this we will divide this given mass by the atomic mass of aluminum. Hence, the number of moles in 54 g of Al is 2 moles.

## How many moles are present in 54g of he?

The correct answer is 13.5 Mole. 13.50 Moles are present in 54g of He.

## How many moles are in aluminum?

One mole of Al atoms has a mass in grams that is numerically equivalent to the atomic mass of aluminum. The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g.

## How many moles are there in 81g of aluminium?

Reason : 81 g of aluminum contains 3 moles of aluminum , which will contain 3×6.023×1023 atoms.

## How many moles are in 54g of H2O?
