Liquid helium at 4.20 K has a density of 0.147 g/mL. Suppose that a 1.50 L metal bottle at 110 K contains air at 3.0 atm pressure. If 50.0 mL of liquid helium are added to the bottle, and the bottle is then sealed and the entire system is allowed to warm to room temperature 25°C, what is the final pressure inside the bottle? Enter units.
