Question

A vessel contains 120 g of oxygen at a pressure of 3.00 atm at 25°C. (a) What is the final pressure if 5.00 g of hydrogen are added at the same temperature without changing the volume of the container? (b) If the mixture in (a) is then exploded and allowed to cool back to 25°C, what will be the pressure of the gas in the vessel?

Step 1

For oxygen: Molar mass of O2 = 32 g/mol Number of moles of O2 = (120 g) / (32 g/mol) = 3.75 mol For hydrogen: Molar mass of H2 = 2 g/mol Number of moles of H2 = (5 g) / (2 g/mol) = 2.5 mol Now, we can use the ideal gas law (PV = nRT) to find the volume of the Show more…
