Q) Which experimental steps can a student perform to be sure that all the water has been removed from the hydrate?

Hi I did the 'dehydration of an inorganic salt hydrate' experiment.

I heated MgSO4 hydrates for 10 minutes, and I weighted the gram of MgSO4 and water.

I realized that all my results were different by trials.

So, I don't know what should I do to make sure that all the water has been removed.

My answer is

Calculate the percentage of water mass in hydrates, and compare with the true value of 'the percentage of water mass in hydrates'. If the error percentage is low, it means that water is removed from the hydrate well.

Am I right?

Thank you.
