- Given that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 0.78 N2, 0.21 O2, and 0.010 Ar, what is the density of air at standard temperature and pressure?arrow_forwardThe density of air at 20C and 1.00 atm is 1.205 g/L. If this air were compressed at the same temperature to equal the pressure at 50.0 m below sea level, what would be its density? Assume the barometric pressure is constant at 1.00 atm. The density of seawater is 1.025 g/cm3.arrow_forwardWhat possible uses exist for the natural gas liquids that are removed from natural gas during its processing?arrow_forward
- Describe what happens to the average kinetic energy of ideal gas molecules when the conditions are changed as follows:(a) The pressure of the gas is increased by reducing the volume at constant temperature.(b) The pressure of the gas is increased by increasing the temperature at constant volume.(c) The average velocity of the molecules is increased by a factor of 2.arrow_forwardHydrogen gas is collected over water at 23.5 °C and an atmospheric pressure of 765 mmHg. Calculate the partial pressure of hydrogen gas.arrow_forwardA metal cylinder with a capacity of 6.0 L is filled with compressed propane (C3H8). The pressure and temperature of the cylinder when it was initially filled were 120 atm and 75 ◦C, respectively. The molar mass of carbon is 12 g·mol−1 and the molar mass of hydrogen is 1 g·mol−1. a) How many moles of propane are in the cylinder? b) What is the mass of the propane inside the cylinder? c) After some time, the cylinder and its contents cool to 25 ◦C. What is the pressure in the cylinder after it has cooled?arrow_forward
