CO2 + 4 H2=CH4 + 2 H2O
The ratio between CO2 and CH4 is 1 : 1
Moles CH4+25.1
The ratio between H2 and H2O is 4 : 2
Moles H2= 19.1 x 4/2= 38.2
An acid, example: “hydrochloric acid”
N=1.2·10²⁴
Nₐ=6.0221·10²³ mol⁻¹
n₂(H₂O)=4 mol
n₁(H₂O)=N/Nₐ
n=n₁+n₂=N/Nₐ+n₂
n=1.2·10²⁴/6.0221·10²³ + 4 = 5.99 mol
5.99 <span>moles of water are in the glass</span>

Molecules :
The mass of substance which consists the equal number of particles as 12 grams of Carbon-12 is said to be mole.
For example:
The balanced chemical equation for production of water from hydrogen and oxygen is:
That means 2 moles of reacts with 1 mole of to give 2 moles of .
The given formula is .
Hence, 4 represents the number of moles in formula that is 4 moles of .
