I got injured while playing football and had to miss a Thermodynamics-I lecture. Got the notes afterwards but they tend to make things more complicated. The notes starts with :-

[tex]Pv=RT[/tex]

Which R is this the Universal Gas Constant or the Individual Gas Constant ?

Is the Molar Volume and Specific Volume same thing?

Then it says [tex]R = \frac{R_{u}}{Mol Wt.}[/tex], which seems alright.

Then it says that :-

For EE :-

[tex] R = \frac {1545}{Mol Wt.} [/tex]

For SI :-

[tex] R = \frac {8314}{Mol Wt.} [/tex]

Question is that I have always seen the Molar Gas Constant to be [tex] 8.134 JK^{-1}mol^{-1}[/tex]. How does 8314 come ?

I'll be obliged if someone can give systematic answers. this way my confusion will be eliminated.

(looks like there's some problem with LaTex)
