Question

In chemistry, n molecules of an ideal gas have pressure (P), volume (V), and temperature (T) that stand in the following relation, where R is a constant. Solve the equasion for n, the number of molecules.

Answer 1

I assume you refer to the 'Perv Nert' equation: $PV=nRT$

Solving for n, $n=\frac{PV}{RT}$
