Help answering this a level questionWatch
sorry this is a silly question but where does it say it's in m3? But thank you!
The ideal gas equation (pV=nRT) will always give/ require volume to be in m^3 just as pressure must be in Pa, and temp in K. To convert the volume that you got (0.0111 m^3) to dm^3 you multiply by 1000. You've done the right working, just didn't finish it off by converting to the correct units
With strict SI units you have volume in m3 and pressure in Nm-2 (Pa)
With the units often used in chemistry you have volume in dm3 and pressure in kPa.
You need to pay attention to the pressure given as this will give yo the volume units.
You should be thankful as a few years ago you could also have pressure in atm, which gives a different value for R (different units), or even pressure in mmHg (Torr).
At least now things are a little more standardised...
