**DrBob222**, Friday, October 26, 2012 at 3:12pm1) Use PV = nRT. You have P, R, T (must be in kelvin) with total n = 0.500+0.300+1.200 = ? Solve for V in L.

2) You meant constant T I assume (instead of consistent T). Multiply V in part 1 by 0.25 and use PV = nRT again. This time V is the new number (multiplied by 0.25), solve for P in atm, n, R, and T are the same as in part 1.
