A cylindrical container of volume $4.0 \times 10^{-3}\text{ m}^3$ contains one mole of hydrogen and two moles of carbon dioxide. Assume the temperature of the mixture is 400 K. The pressure of the mixture of gases is:
[Take gas constant as $8.3\text{ J mol}^{-1}\text{K}^{-1}$]
(1) $24.9 \times 10^3\text{ Pa}$
(2) $249 \times 10^1\text{ Pa}$
(3) $24.9 \times 10^5\text{ Pa}$
(4) 24.9 Pa
