Questions
At constant temperature, a 1 L vessel is filled with 125 ml of a gas at 0.6 atm and 150 ml of another gas at 0.8 atm. Now, if the temperature remains constant, find the total pressure of the mixture at equilibrium:
detailed solution
Correct option is C
From the ideal gas equation we know that PV=nRTwhere n = number of molesR = gas constantFrom the above equation we can say thatn=PVRTSo for the mixture we can write⇒n=n1+n2⇒PVRT=P1V1RT+P2V2RTSubstituting the given values of variables in the equation.P×1=0.60×0.125+0.80×0.150P=0.0750+0.120P=0.195 atmTalk to our academic expert!
