Which equation is used to form the combined gas law?

The ideal gas equation

Explanation:

The ideal gas equation is derived from the combination of three gas laws:

The ideal gas law is expressed mathematically as: PV=nRT where:

P is pressure

V is volume

n is the number of moles

R is the ideal gas law

T is temperature.

To obtain the combined gas law, we assume that n=1 and this gives:

                        = R

Therefore:

=
