What is the total pressure in atmospheres when 0.400 g of H₂, 2.00 g of N₂, and 10.5 g of CO₂ are injected into a 10.0 liter flask at 273 K?

Question

Quizplus · Accepted Answer

To find the total pressure, use the ideal gas law PV = nRT for each gas and sum their partial pressures. Calculate moles for each gas: H2 (0.400 g / 2.02 g/mol), N2 (2.00 g / 28.02 g/mol), CO2 (10.5 g / 44.01 g/mol). Use R = 0.0821 L·atm/mol·K and T = 273 K. Sum the pressures to get the total pressure.
