Post Lab-Determination of a Chemical formula Is the formula of the hydrate depend upon the amount of hydrate initially stated with? Explain. What Law supports your conclusions?
Homework Answers
Yes, Formula of mass depend on amount of hydrate initially stated. Formula of hydrate can be deduced by subtracting mass of anhydrous sample from initial sample mass.
This support law of conservation of mass which state mass can neither be created nor be destroyed.
