WebMethod 1: Finding total pressure by assuming there is only one gas in the container. Because, we assume that A and B gases behave as ideal gases. Therefore, we can apply ideal gas law for the overall system considering there are total of 30 mol in the system. P T V = nRT. P T * 1 = 30 * 8.314 * 400. P T = 99768 Pa.
