112 ml of hydrogen gas, measured at 22°C and 1.9 atm pressure, and 222 ml of nitrogen gas, measured at 22°C and 1.9 atm pressure, were forced into the 112 ml container at 22°C, what would be the pressure of the mixture of gases now in the 112 ml container? Enter to 2 decimal places.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.
