A student is asked to determine the degree of hydration of a salt by finding the mass of a clean dried crucible and lid followed by the mass of the crucible and lid containing a sample of the salt. The crucible, lid and salt are heated in a Bunsen burner flame, cooled, and weighed. If the crucible, lid and salt are heated only once instead of the recommended three times, what will be the effect on the degree of hydration compared with the actual value?
