Answer:

0.6425 moles of NH_3 is required to react with 25.7 grams of O_2.

Explanation:

mas of oxygen gas = 25.7 g

moles of oxygengas = \frac{25.7 g}{32 g/mol}=0.8031 mol

4NH_3 (g)+5O_2 (g) \rightarrow 4 NO(g) + 6H_20 (I)

According to reaction given above,  5 moles of oxygen gas reacts with 4 moles of ammonia gas.

Then 0.8031 moles of oxygen gas will react with :

\frac{4}{5}\times 0.8031 mol=0.6425 mol of ammonia gas

0.6425 moles of NH_3 is required to react with 25.7 grams of O_2.
