You appear to be using "R" both on the left as the gas constant and on the right as a temperature measurement. Is that correct? And does the "R" as temperature mean degrees "Reamur" or "Rankine"
You find a useful equation in an old textbook. There is a sample calculation but suspect that the value of the universal gas constant used is wrong. what is the correct value in these units.
I don't know, I have never heard of the terms 'reamur' or rankine', were just covering dimensional analysis/ unit conversion in class. I copied this question straight out of my work book.
I am not able to make sense of this myself, but others in my class got the correct answer.
