A helium gas (He) leak resulted in a rectangular vessel (200 cm x 20 cm x 10 cm) becoming pressurized at a temperature of 20 °C with 400 g of helium. Given that the van der Waals constants for helium (He) are: a (L2 atm mol-2) = 0.034b (L mol-1) = 0.02370 (i) Calculate the pressure exerted by the helium gas in the vessel. (ii) Calculate the root mean square speed of a He atom at 20 °C.
