    Hey I'm studying OCR A chemistry and I was wondering if anyone could recommend any resources for STP and RTP calculations because my textbook and revision guide does not cover them.
    Thanks in advance.

    I'll bet that, since the textbook don't cover them, they aren't required knowledge for the specification.

    Actually, I happen to know that you're expected to do calculations using 24 dm3 mol-1 (i.e. at RTP) and using PV = nRT (i.e at any T and P). Those calculations will be in the year 1 text book. STP (whatever OCR define as standard!) calculations are not on the spec.

    you can use the gas laws,
    assuming you know molar volume at rtp = 24 dm3 per mole

    then you want to find molar volume at stp (which you should already know is 22.4 dm3 per mole),

    set the correct T and p for stp vs rtp...and your molar volume at stp would be the "unknown".
