A carbon dioxide sample weighing 44.0 g occupies 32.68 l at 65°c and 645 torr. what is its volume at stp?

Combined gas law,

[tex] \frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}} [/tex]

[tex] \frac{(645torr)(32.68 L)}{338 K} = \frac{(760 torr)V_{2}}{273 K} [/tex]

[tex] v_{2}=22.4 L [/tex]

So, the gas will occupy 22.4 L at STP
