Helpppp me pleaseeeeeee❣️

In this question, we're given an equation (P = R / V) and a graph. We can utilize both of these in order to find R.

We can start off by changing the equation so that R is isolated, or by itself.

P = R / V

By multiplying both sides by V, we can get rid of the pesky denominator:

P*V = R*V / V
P*V = R
R = P*V

That wasn't so bad, was it?

Since we've also been given a graph with all of the values, we can use those to solve for R.

If you looked at the bottom of the question, you'll realize that all of the letters have been assigned units.

P = pressure
V = volume
R = universal gas constant

Since the graph provides values for P and V, we can input those into the equation we created:

R = P*V
R = 2*4.155
R = 8.31

Since the value of R will stay the same in the graph, there's no need to check the other numbers. (If you would like to double check, you could run the variables through our equation to see if R is still the same)

the answer is exterior angle :)
