Assume that 13.5 g solid aluminum (al) react with hcl to produce solid aluminum chloride (alcl3) salt and gaseous hydrogen (h2) at standard temperature and pressure. how many moles of al react? mol how many moles of h2 are produced? mol how many liters of h2 are produced? l

Answer : The moles of Al is, 0.50 mole.

The moles of is, 0.75 mole.

The volume of is, 16.8 liters.

Explanation : Given,

Mass of aluminum = 13.5 g

Molar mass of aluminum = 26.98 g/mole

First we have to calculate the moles of aluminum.

The moles of Al is, 0.50 mole.

Now we have to calculate the moles of .

The balanced chemical reaction will be,

From the balanced reaction, we conclude that

As, 2 moles of Al react to give 3 moles of

So, 0.50 moles of Al react to give moles of

The moles of is, 0.75 mole.

Now we have to calculate the volume of .

At STP,

As, 1 mole of contains 22.4 L volume of

So, 0.75 mole of contains volume of

The volume of is, 16.8 liters.
