Determine which of the following contains the greatest mass of aluminium: 122 g of alpo4, 266 g of a12c16, or 225 g of
a12s3.

Answer : The contains the greatest mass of aluminum.

Explanation :

For :

Molar mass of = 122 g/mole

Molar mass of aluminium = 27 g/mole

As, 122 g of contains 27 g of Al

So, 122 g of contains of Al

The mass of 'Al' in is, 27 grams.

For :

Molar mass of = 266.7 g/mole

Molar mass of aluminium = 27 g/mole

As, 266.7 g of contains of Al

So, 266 g of contains of Al

The mass of 'Al' in is, 54 grams.

For :

Molar mass of = 150 g/mole

Molar mass of aluminium = 27 g/mole

As, 150 g of contains of Al

So, 225 g of contains of Al

The mass of 'Al' in is, 81 grams.

Hence, from this we conclude that contains the greatest mass of aluminum.
