What are the major types of stoichiometry problems?

what is Boyles Law
when a gas is pumped into an enclosed space, it will shrink to fit into that space, but the pressure that gas puts on the container will increase.
Why is solution stoichiometry significant?
Stoichiometry is important in analytical chemistry, analysis methods, and understanding chemical reactions. Stoichiometry is applied in methods such as gravimetric analysis, titrimetric analysis, and many more.
A science of mapping changes in state variables of a body for the reason of deriving heat transfer, related to the changes in is state due to physical changes, chemical reactions is called
Calometer
