**DrBob222**, Monday, October 17, 2011 at 9:17pmOne way to do this is to use PV = nRT and solve for n = PV/RT.

Calculate n for one bulb and n for the other bulb, add the two and calculate P from PV = nRT using the sum of the bulbs for n. I get 3.5. What do you use for R and T. Whatever values are convenient because they end up canceling.

Another way is to look at the equation for n = PV/RT. Since T is a constant and R is a constant, we can just leave them out of the equation.

Then n1 = PV = 2*2 = 4

n2 = 3.5*4 = 13.5

Total n = 17.5

17.5 = PV. V is the total of 3L + 2L = 5L. Solve for P.
