$C a C {O}_{3} \left(s\right) + \Delta \rightarrow C a O \left(s\right) + C {O}_{2} \left(g\right) \uparrow$
We have a $25 \cdot g$ initial mass of $\text{calcium carbonate}$ and $\text{sodium hydroxide}$. We need a FINAL mass that represents the mass of $\text{calcium oxide}$ and $\text{sodium hydroxide}$ to address your question. The LOST mass represents what?
