Universal and Individual Gas Constant

[Altairs]

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 :-

$$Pv=RT$$

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 $$R = \frac{R_{u}}{Mol Wt.}$$, which seems alright.

Then it says that :-

For EE :-

$$R = \frac {1545}{Mol Wt.}$$

For SI :-

$$R = \frac {8314}{Mol Wt.}$$

Question is that I have always seen the Molar Gas Constant to be $$8.134 JK^{-1}mol^{-1}$$. 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)

It could be either, depending on whether v is the volume per mole or the volume per unit mass.

Is the Molar Volume and Specific Volume same thing?

Molar Volume is volume per mole and Specific Volume is volume per unit mass

Then it says $$R = \frac{R_{u}}{Mol Wt.}$$, which seems alright.

It's not clear. It could be a typo.
