The thing with is that you don't have a standard interval of accepted values that you can use as a reference for every experiment you do.

Percent error depends on the application itself. More specifically, percent error depends on what measurement limitations your experiment has.

For high school level chemistry labs, a percent error that revolves around $5%$ is actually a good result.

Of course, this depends on the requirements set by your instructor.

If your equipment allows for very accurate measurements, your target percent error could go as low as $1-3%$. Otherwise, percent errors of $10-15%$ can be considered acceptable as well.

Your values correspond to a $38.169%$ water for copper(II) sulfate pentahydrate. The accepted value is about $36.075%$, so I would say that your results are not ideal, but that they should fall within the accepted range.

Again, that ultimately depends on what your instructor considers acceptable.
