Make a prediction about the densities of the unknown solid and liquid. How will mass affect the volume of the solid, and how will volume affect the mass of the liquid? For better clarification I added the top of the assignment so you have exactly what I'm working with. Thanks in advance!!

you didnt put any of the following

what is the question here. i think you messed up.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
