Answer 1

Answer:

$r=\dfrac{PV}{nT}$

Step-by-step explanation:

The given equation is :

$PV=nrT$

Where

P is pressure

V is volume

n is no of moles

r is Gas constant

T is temperature

We need to solve the above equation for r.

Dividing both sides of the above equation by (nT). So,

$\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}$

So, the value of r is equal to $\dfrac{PV}{nT}$.
