A gas balloon has a volume of 106.0 liters when the temperature is 45.0C and the pressure is 740.0 mmHg. What will its volume be at 20.0C and 780.0mmHg pressure?

#92.66L#

Explanation:

Applying ideal gas equation considering the gas inside the balloon to be ideal,to get the new volume,

So,from ideal gas law,we get,

#(PV)/T #= constant

so,we can say,
#(PV)/T = (P'V')/(T')#

Where, #P=740 mm of Hg,P'=780 mm of Hg,T=(45+273)=318K,T'=(20+273)=293K,V=106L#

So, #V'=92.66 L#
