Question

How much mass of aluminium can be obtained from 0.1 mol of Al2(SO4)3

Answer 1

Explanation:

0.2 mole of Al

0.2 *23.

4.6

Answer 2

5.4 g of aluminium can be obtained from 0.1 mole of $Al_2(SO_4)_3$.

Given:

Number of moles = 0.1

Formula of the compound = $Al_2(SO_4)_3$

To find:

Mass of aluminium = ?

Formula to be used:

• $Mass = No. of moles\times Molar mass$
• $No. of moles = \frac{Given mass}{Molar mass}$

Calculation:

• To find mass of $Al_2(SO_4)_3$, molar mass is required. Thus

The molar mass of $Al_2(SO_4)_3$

= (2× 27) + (3 × 32) + (12 × 16)

= 54 + 96 + 192

= 342

Mass = 0.1 × 342 = 34.2g

No. of moles of Al = $\frac{34.2}{342}\times 2 = 0.2$

To obtain mass from moles, the following formula must be applied:

Mass of Al = Molecular mass of Al × No. of moles

Mass of Al = 27 × 0.2

Mass of Al = 5.4

Conclusion:

Thus it is inferred that from 1 mole of $Al_2(SO_4)_3$, 5.4g of aluminium can be obtained.
