the pressure inside each of two identical cylinders is equal to atmospheric pressure. one cylinder contains hydrogen, the other
ycow [4]

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

\frac{P_1 V_1}{P_2 V_2} \:=\: \frac{n_1 RT_1}{n_2 RT_2}

\frac{P_1 V_1}{P_2 V_2} \:=\: \frac{n_1 T_1}{n_2 T_2}

n₁ = n₂

So the total amount of hydrogen gas is equal to total amount of ideal nitrogen gas.
