A room of volume 68 m^3 contains air having an average molar mass of 36.3 g/mol. If the temperature of the room is raised from 17.2C to 25C, what mass of air will leave the room? Assume that the air pressure in the room is maintained at 43.6 kPa. Answer in units of kg.
Been messing around with the following to get it into the right form, am I on the right track?
[tex]P_0V = n_1RT = \frac{m_1}{M}RT_1[/tex]
[tex]P_0V = n_2RT_2 = \frac{m_2}{M}RT_2[/tex]
[tex]m_1-m_2 = \frac{P_0VM}{R} \times (\frac{1}{T_1}-\frac{1}{T_2})[/tex]
