A useful dilution relationship is (M1V1)=(M2V2) where M is molarity and V is volume in liters.
(6.00M x V1) = (2.00M x .500L) (I assume you mean 2.0M)
V1= (2.00M x .500L)/6.00M
V1= 0.167L
Answer:
Pressure will increase by the direct ratio of the volume change. Therefore, since volume changes from 145 to 80, pressure will go up by the ratio change 145÷80 times the original pressure 125 kPa. Sure, you can use the more complicated gas law equation PV = nRT but we are only varying volume so the question boils down to the change in one simple variable.
Putting them together we have: 145÷80 x 125 = 226.5625 or just 226 kPa since the accuracy of the figures and the equation are not great.
