yes I used k for temperature and the right constant value

okay i realized that and fixed it but i still get the wrong answer...i used 14.7 g this time

Liquid helium at 4.2 K has a density of 0.147 g/mL. Suppose that a 2.50-L metal bottle that contains air at 105K and 2.0 atm pressure is sealed off. If we inject 100.0 mL of liquid helium and allow the entire system to warm to room temperature (25 °C), what is the pressure inside the bottle...
