The correct answer is option e.

Explanation:

$P_4+ 5O_2 \rightarrow P_4O_{10}$

Moles of phosphorus pent-oxide :

$\frac{14.2 g}{284 g/mol}=0.05 mol$

According to reaction, 1 mole of phosphorus pent-oxide is obtained from 5 moles of oxygen gas.

Then 0.05 mole of phosphorus pent-oxide will be obtained from:

$\frac{5}{1}\times 0.05 mol=0.25 mol$

Hence,the correct answer is option e.
