Hey, Does anyone know for ocr a a level chemistry if you need to know the values for standard room temp and pressure? If so, what are the exact values because my notes and the textbook say different . Thank you

First the units Pressure is in KPa Volume in m3 (cm3 x 10^-6 -> m3) (dm3 x 10^-3 -> m3) Temperature in K
If you are using pV = nRT, you will not need to use it if it is at RTP Volume = Vm x moles where Vm = 24000 cm3 = 24 dm3 (the volume gas equation you learnt at gcse works only at RTP)
Did you get RTP values mixed up with standard values used for enthalpy changes?
