a gas has a volume of 0.785L at 20.1 celsius and 1.00atm. What is the volume in liters of this gas at a temperature of 121 celsius and a pressure of 1.80 atm?
Volume of the gas=0.785L
Temperature =293.25K
Pressure =1.00atm
According to the Gas law that, PV=nRT
Gas Constant = 0.082 Latm mol-1 K-1
So number of moles =1*0.785/293.25*0.082=0.033 moles
At 1.8atm and 394.15K
Volume V=nRT/P = 0.033*0.082*394.15/1.8 = 0.592L
