If you had excess chlorine, how many moles of aluminum chloride could be produced from 12.0g of aluminum

Respuesta :

Answer:

Hence, 0.455 mol of aluminum chloride could be produced from 12.0 grams of aluminum.

Explanation:

Given data:

•Mass of aluminum is 12.0 grams.

To find:

•Number of moles of aluminum chloride produced from Al.

The given reaction is as follows:

2A1+ 3Cl₂ → 2AlCl3

First, we have to find the number of moles of aluminum by the relation given below:

n = m M;

Where:

•n is the number of moles.

•m is the mass in grams.

•M is the molar mass in g/mol.

The molar mass of Al is 26.98 g/mol. Substitute the values in above equation to obtain the number of moles of aluminium as follows:

n = (12.0g)/(26.98g /mol)

= 0.445 mol

From the reaction stoichiometry, we can see that 2 moles of Al forms 2 moles of aluminium chloride (A1C13). This means, the number of moles of Al and AlCl3 is equal.

So, 0.445 mol Al will give 0.455 mol AlC13.
