Question

The equation below shows hydrogen reacting with oxygen to produce water. 2H2+O2>2H2O if 16mol of oxygen were reacted with excess hydrogen gas, how many moles of water would be produced?

Answer 1

in a chemical equation the coefficients represent the ration of the number of moles. therefore, if you have 16 moles of oxygen, you would have 32 moles of water.

Answer 2

Answer : The number of moles of water produced would be, 32 moles.

Explanation : Given,

Moles of $O_2$ = 16 mole

The given chemical reaction is:

$2H_2+O_2\rightarrow 2H_2O$

From the balanced chemical reaction we conclude that,

As, 1 mole of $O_2$ gas react to give 2 moles of $H_2O$

So, 16 mole of $O_2$ gas react to give $16\times 2=32$ moles of $H_2O$

Thus, the number of moles of water produced would be, 32 moles.
