Fit a probability density function and GOF

I have binned data that form a probability density function.
I managed to fit this data to a normal PDF using MLE.

Now I want to somehow evaluate the goodness of fit, i.e. something
that would tell me
quantitatively that the shape of my experimental PDF is reasonably
well described by a normal PDF.

Given that I dont have access to the original data (nor the number of
counts for each bin)...how can I do that ?

As a basic example, suppose I have data like this:

Bins Probability
10 0.1
12 0.2
14 0.4
16 0.2
18 0.1
