The number of moles of hydrogen is equal to the number of moles of nitrogen.
According to the ideal gas equation
PV = nRT
where
- P = the pressure of the gas
- V = the volume of gas
- n = the total amount of ideal gas (moles)
- R = the universal gas constant
- T = the temperature
In the problems there are two identical cylinders means, V₁ = V₂
The pressure inside each of two identical cylinders is equal to atmospheric pressure means, P₁ = P₂
Both gases are at the same temperature, means T₁ = T₂
n₁ = n₂
So the total amount of hydrogen gas is equal to total amount of ideal nitrogen gas.
