Two gases argon 30.6 grams and carbon monoxide 8.8 grams are confined in a container at a pressure of 960.0torr. Compute the partial pressure of argon in torr. You may require looking up the formula for one or both of your gases.
Liquid helium at 4.2 K has a density of 0.147 g/mL. Presume that a 2.00-L metal bottle that contains air at 108K as well as 3.0 atm pressure is sealed off. If we inject 90.0mL of liquid helium and permit the entire system to warm to room temperature (25°C), define what is the pressure inside the bottle?
