5.5 Pressure of 1 g of an ideal gas A at is found to be 2 bar. When 2 g of another ideal gas B is introduced in the same flask at the same temperature the pressure becomes 3 bar. Find a relationship between their molecular masses.
Given Pressure of 1g of an ideal gas A at is .
When 2g of another ideal gas B is introduced in the same flask at the same temperature,
The pressure becomes .
We can assume the molecular masses of A and B be respectively.
The ideal gas equation,
So, we have and
Hence the relation between the two gases is .
