Answer:
It is required 0.3 molecules of O2 to produce 0.6 molecules of H2O
Explanation:
The water´s formation reaction is: 2H2 + O2 --> 2H2O
This reaction shows the molecular O2:H2O ratio: 1:2.
Then, if we want to know how many molecules of O2 are required to produce 0.6 of H20, it is necessary calculate as it showed next:
0.6 molecules H2O * (1 molecula O2 / 2 molecules H2O)= 0.3 molecule O2
