Answer
41.41 $cm^{3}$ is the volume of 33 g sample of this liquid in $120^{o}$C.
Work Step by Step
From formula for density
d = $\frac{m}{V}$ , we can write the formula to find the volume : V = $\frac{m}{d}$
We see the density of the liquid changes when it is heated. We are given the density 0.797 $\frac{g}{cm3}$when the liquid is in temperature $120^{o}$C.
So the volume of 33 g sample of this liquid in this temperature would be:
V = $\frac{m}{d}$
V = $\frac{33 g}{0.797g/cm3}$
V= 41.405 $cm^{3}$
Considering significant figures:
V= 41.41 $cm^{3}$
41.41 $cm^{3}$ is the volume of 33 g sample of this liquid in $120^{o}$C.
