The pressure of a mixture of nitrogen, carbon dioxide, and oxygen is 380. kPa. What is the partial pressure of oxygen if the partial pressure of the nitrogen and carbon dioxide are 200. kPa and 32 kPa, respectively?

a gas mixture contains sulfur hexaflouride at a pressure of 2.64 atms and diphosphorus pentoxide at a pressure of 1.58 atms. what is the mole fraction of diphosphorus pentoxide in this mixture?

A 7.00 L tank at 15.8 °C is filled with 5.07 g of sulfur tetrafluoride gas and 11.5 g of sulfur hexafluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. Round each of your answers to 3 significant digits. mole fraction: x10 sulfur tetrafluoride partial pressure: || atm mole fraction: sulfur hexafluoride partial pressure: atm Total pressure in tank: atm

In an ideal gas experiment performed with some modifications, the students used0.029 g of aluminum foil instead of magnesium ribbon. They prepared the eudiometer by adding 6M HCl andfilling it with water to the brim. Once the setup was complete, they performed theexperiment. Note that the aluminum was completely consumed in the reaction.From the experiment, it was found that the external pressure was 1.05 atm at30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The waterlevel inside the eudiometer is 4.15 cm below the surface of the water leveloutside. ● At 30.0 °C, Pvapor = 31.8 mmHg● R = 0.08206 L-atm/mol-K = 62.36 L-torr/mol-K● MWAl = 26.98 g/mol Find the value of the pressure of dry air (PDA) in torr and give the balanced chemical reaction of the aluminum metal with the acid.
