Answer:

8.96 L of H₂

Explanation:

From the question given above, the following data were obtained:

Number of mole of H₂ = 0.4 mole

Volume of H₂ at STP =?

We can obtain the volume of H₂ at STP by doing the following:

Recall:

1 mole of a gas = 22.4 L

Thus,

1 mole of H₂ = 22.4 L

Therefore,

0.4 mole of H₂ = 0.4 × 22.4

0.4 mole of H₂ = 8.96 L

From the calculations made above, 0.4 mole of H₂ is equivalent to 8.96 L of H₂
