The temperature, pressure and volume of two gases X and Y are T, P and V, respectively. When the gases are mixed then the volume and temperature of mixture remains V and T, respectively. The pressure and mass of the mixture will be :
Answer & explanation
Correct answer: option 1
From Dalton's law,
Pressure of mixture = P1 + P2 = P + P = 2P
Similarly, mass also will become double i.e. 2M
