PV = nRT p = nRT/V pA = 1.25*0.08206*(273.2 + 32.8)/6.01 = 5.22 pB = same thing. When you have a problem like this it is better for you to show your work so we can find the error. Otherwise, we're shooting in the dark. It's easier for us to find the error than it is fo...
Dinah, I worked one JUST LIKE this yesterday for you (both the short way and the long way). You should be able to see the connection and not ask for help when it's the same type problem.
Go to Google. Type in "3.0 meters to yards" without the quotation marks and hit the enter button. Up pops the answer.
The easy way to do this is p 3rd gas = nRT/V, then pA + pB + p3rd = Ptotal. You can do it the long way this way. n gas A = PV/RT. n gas B = PV/RT n third gas = 0.250 ntotal = nA + nB + n3rd. Then Ptotal = nRT/V You should get the same answer either way. I believe the answer is...
Use PV = nRT. Substitute and solve for volume.
Use PV = nRT; substitute n = 1.48 and solve for p gas A. Substitute n = 4.80 and solve for p gas B. Remember T must be in kelvin.
In brief, this is what you do. Let me know where you need additional help but show your work from the beginning to the point you need help. You need to convert 0.48g CO2 to g C. Convert 0.1636g H2O to g H (not H2). Convert 0.0618g NH3 to g N (not N2). a. gC + gH + gN = 0.2 wou...
You must have a table or graph (or something) in your text/notes that gives the solubility at 30 C and 60 C. I don't have those tables available. If you want to type that info in I can show you how to work the problem.
See your other post.
I would take the average of 0.084 and 0.057 and see if that gets close to pH = 2.5. Avg = about 0.07% = 0.007g/100g mols H3PO4 = 0.07/98 = about about 7E-4 and that in 0.1L (if density is about 1.0) that makes 7E-3M Then H3PO4 ==> H^+ + H2PO4^- I.....7E-3......0.......0 C.....
