Question

Solve PV= nRT for n.
A. PV/RT=n
B. RT- PV=n
C. RT/PV=n
D. PV- RT=n

Answer 1

A - PV/RT = n

Explanation:

The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.

Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.

PV = nRT

Divide both sides by R

PV/R =nT

Divide both sides by T

PV/RT = n

And now, the variable n has been isolated and the new equation to solve for moles is presented.

Hope this helps!
