use PV=nRT where n is the total number of moles. Use V=25.00 L P =1.00 atm you needed to calculate n for the first part. Make sure that use the correct value for R based on the units.

I don't understand the question. Is the first statement and the second a continuation? That is, is the S containing compound the same as the 140 g of the gas? Use PV = nRT to calculate n. Then use n = grams/molar mass and calculate molar mass. Use 29% S and 71% F to determine ...

I know how to use the equations pv=nrt and P1xV1/n1xT1 = P2xV2/n2xT2, but I don't understand when to use them. I have a test tomorrow and I'm going over some word problems, but I can't figure out how decide which formula you need to use. Is there a specific way to know?

I don't think you can use graphs. I'd use pictures -- perhaps starting with slavery times. You could use pictures of segregation and the fight for integration. Of course, your last pictures could be of President Obama.

Use PV = nRT. There is no pressure listed but make up one to use (the easiest is to use 1 atmosphere). n = grams/molar mass. Solve for volume. Then use PV = nRT again, this time using P = 1/2 what you used in the first case, change T to the new temperature, and solve for n. ...
