Question

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.

Answer 1

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

Answer 2

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?

Answer 3

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

Answer 4

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?

Answer 5

You have it.

Answer 6

Makes sense now. Thank you.
