Find the number of moles of water that can be formed if you have 126 mol of hydrogen gas and 58 mol of oxygen gas.

Answer : The number of moles of water formed can be 116 moles.

Explanation :

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction will be:

From the balanced chemical reaction we conclude that,

As, 1 mole of react with 2 mole of

So, 58 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of

From the reaction, we conclude that

As, 1 mole of react to give 2 mole of

So, 58 moles of react to give moles of

Therefore, the number of moles of water formed can be 116 moles.
