If you had excess chlorine, how many moles of of aluminum chloride could be produced from 12.0 g of aluminum? express your answer to three significant figures and include the appropriate units.

Answer : The  number of moles of aluminium chloride will be 0.444 moles.

Solution : Given,

Mass of Al = 12.0 g

Molar mass of Al = 27 g/mole

First we have to calculate the moles of Al.

Now we have to calculate the moles of

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 2 mole of react to give 2 mole of

So, 0.444 moles of react to give 0.444 moles of

Therefore, the number of moles of aluminium chloride will be 0.444 moles.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
