### Units of ln[A] axis

When we take ln[A] to plot it in a graph against time to determine the order, is it implicitly understood that we take it as $ln(\frac{C}{C^{o}})$, where $C^{o}$ is the standard molarity, to cancel out the units? If not, in what units do we measure the axis ln[A]?

Yes, that's the assumption because the result of a logarithm is a pure (unitless) number.
