Question

How many moles of water can be formed from 23.9 mol of oxygen gas?

H2 + O2 --> H20
Hint: Is it balanced?

Answer 1

47.8 moles of H₂O.

Step-by-step explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2H₂ + O₂ —> 2H₂O

From the balanced equation above,

1 mole of O₂ reacted to produce 2 moles of H₂O

Finally, we shall determine the number of mole of water, H₂O, produced by the reaction of 23.9 moles of O₂. This can be obtained as follow:

From the balanced equation above,

1 mole of O₂ reacted to produce 2 moles of H₂O.

Therefore, 23.9 moles of O₂ will react to produce = 23.9 × 2 = 47.8 moles of H₂O.

Thus, 47.8 moles of H₂O were obtained from the reaction.
