Verified Answer :

There are 0.213 moles of FeF3 present in 24 grams.

Moles

It is a standard scientific unit for determining the large quantities of very small entities like molecules, atoms, or other particular particles.

Based on the given information:

  • The mass of FeF3 given is 24 grams.

Now the molar mass of FeF3 is,

\(= (1*55.84+3*19)g/mol\\= (55.84+57.00) g/mol\\= 112.84 g/mol\)

The formula to find the number of moles of FeF3 is,

\(Number of moles = \frac{Mass}{Molecular mass}\)

Now putting the values we get,

\(Number of moles = \frac{24 grams}{112.84 g/mol} \\Number of moles = 0.213 moles\)

Thus, the number of moles in 24 grams of FeF3 is 0.213 moles.

The number of moles in 24.0 grams should be 0.213 moles.

Calculation of a number of miles:

We know that

Number of moles = mass ÷relative mass

Here

Mass be 24

And, the relative mass should be

= 55.8 + 19 + 19 + 19

= 112.8 g/mol

So the no of moles should be

\(= 24 \div 112.8\)

= 0.213 moles
