That is wrong mphetang, gas composition does not define if a gas is ideal or real.

An Ideal gas is a gas whose molecules do not interact, therefore we assume they never have steric interactions or intermolecular interactions.

We typically describe an ideal gas with the expression, PV = nRT

A real gas we assume interacts and undergoes intermolecular interactions therefore modeling a real gas can get quite complex.

In reality though no ideal gas exists but it can still act as a great practical model for some systems that have negligible interactions (relative to what you are trying to determine).
