##### Calculate the inverse volume of a gas
« on: October 17, 2012, 12:44:58 PM »
I appreciate all of the help you guys have given me in the past! However once again I kindly need your help.

I do not know the formula for solving for the calculated inverse volume of a gas. I have been given the pressure of the gas 40.0 lb/in^2 and the volume of the gas 12.0 mL.

Any help would be greatly appreciated.

I would read "inverse X" as 1/X.

Not sure exactly what you are asking as without context it makes little sense.

My apologies sir!

I am supposed to calculate the inverse volume value given the information I have been given.

Pressure of gas = 40.0 lb/in^2

Volume of the gas = 12 mL

I am supposed to solve for the inverse volume of the gas 1/V.

This topic revolves around Lussac and Boyles laws

Once again, sorry.

Perhaps I am missing something as well but if you already know V = 12 mL, then what is the problem calculating 1/V?

So the pressure of the gas is irrelevant?

As far as I can see, yes.

if V = 12 mL, 1/V = (1/12) mL-1

The question also mentioned that the data data was collected for pressure and volume of a gas sample at constant temperature.

Not sure if this information is important.

It might help if you post the whole question in full.

Suppose you collect the following data for pressure and volume of a gas sample at constant temperature. Calculate the inverse volume value when the pressure of the gas is 40.0 lb/in squared and the volume of the gas is 12.0 mL.

If the volume is 12 mL at 40 lb/in2, then 1/V = (1/12) mL-1.

If 12 mL refers to the initial volume, V1, of the gas at an initial pressure P1, and then the pressure has been changed to P2 (= 40 lb/in2), you would have to calculate the corresponding new volume V2.

The question you quoted implies there is a data set that you are not showing.

I can not help you any further unless you post the entire question exactly as you have it - as I have already asked.

I think what you posted was correct.

Thank you, I appreciate it!
