    Find Vol 2 in Ideal Gas Law Problem with V1 and V2 Open and V3 Shut

    For the test, the Mass Flow Controller was programmed to max value to fully open needle valve. There is also a V4 that is opened (that bypasses the MFC)

    Find Vol 2 in Ideal Gas Law Problem with V1 and V2 Open and V3 Shut

    Thanks haruspex. This is in a lab. There is a mass flow controller in the gasline. But this leaves the volume measurement dependent upon the accuracy of the MFC and gas correction factor associated with it. Is there other information I can gather to help solve this ? Thanks Dave, I'm...

    Find Vol 2 in Ideal Gas Law Problem with V1 and V2 Open and V3 Shut

    Please refer to diagram. V1 is open initially then V2 is open for 5 minutes for pressure to equalize. V1 and V2 are then shut. V3 is opened. What is Vol 2 ? P(final)*V(final) = n(final)* R*T => (Vol1 + Vol2) = n(final)*R*25C/ 0.070 Torr where n(final) = n(Vol1) + n(Vol2) If I shut V3, I...
