Does the mass of each element in a compound depend on the amount of compound?
Yes, because the mass of each element in a compound depends on the mass of the compound.
What is the formula for the percent by mass of a compound?
((mass of element)/(mass of compound))*100
What is nitrogen rule?
If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.

Xstudent = mass of a student
Does the mass of each element in a compound depend on the amount of compound?
Yes, because the mass of each element in a compound depends on the mass of the compound.
When the unknown was heated could the decrease in mass have been partly due to the loss of some substance other than water?
yes because water is loss from hydrates compound
