Answer:
71.8 g
Explanation:
With the first sentence we can calculate the density of the sample of glycerol:
[tex]Density=\frac{mass}{volume}[/tex]
[tex]Density=\frac{25.2g}{57mL}\\Density=1.26g/mL[/tex]
Using the density of the sample we calculate the mass of a given volume:
[tex]Volume*Density=Mass[/tex]
57 mL * 1.26 g/mL = 71.8 g
A 57 mL sample of glycerol weighs 71.8 g.
