PV = nRT, what is R, the constant?

What is the R, constant, in terms of kPa and atm? I need to know by tomorrow for my final exam 🙁

  • The R constant for atm is 0.08206 atm; for kilopascals it is 8.314 kPa.

  • R Constant

  • Surely you don’t need to memorise these constants! And the whole point of going over to kPa for pressure was to junk the antiquated “atmosphere”

    Anyway, R is defined as ( volume unit) (pressure unit) K-1 mol-1
