Container A holds 752 mL of ideal gas at 2.40 atm. Container B holds 179 mL of ideal gas at 4.80 atm. If the gases are allowed to mix together, what is the resulting pressure?

Note: Find the partial pressure of each gas in the total volume using a formula that relates volume and pressure. Then sum the partial pressures to get the total pressure.

So what happens if you follow the hint? It tells you what to do as well as I can do it.

I am having trouble trying to figure out what formula I can use to determine the partial pressure of each. Is it Boyle's Law?

P1V1 = P2V2 for gas 1.
P1V1 = P2V2 for gas 2.
Total P = 1 + 2 = ? (not 3 :-).

So would it look like this:

2.40*752=P2*931 for gas 1
4.80*179=P2*931 for gas 2

Then add the two P2's that I get. Right?

You have it.
