1. The problem statement, all variables and given/known data The ideal gas equation, PV=nRT, may have the following units: P is given in bar (bar) V is given in m3 (cubic meters) N is given in mol (moles) T is given in K (kelvin) Which value of R would you use for the calculation if you were using the above units for the other variables in the calculation? 2. Relevant equations Dont have any. 3. The attempt at a solution I have no attempt at the solution as i honestly do not understand how to come to a conclusion. I am a first year university student, having just started a degree in Biochemistry - and i have three basic chemistry modules to complete before i can get onto Biochemistry. This being a career change for me at age 34, and not having done science in school, i am really stuck and have been battling on this question for a week now. Any help would be greatly appreciated - just an explanation of where to start would be of great help. Thanks!
