Answer

Density = 3.755 $\frac{g}{cm^{3}}$

Work Step by Step

Given : Mass = 33.42 g Also, when the pellets are added to water, increase in volume = volume of the pellets, when they are completely submerged in water. (Archimedes principle) Increase in volume = Final volume - Initial volume Final volume = 21.6 mL Initial volume = 12.7 mL Thus volume of pellets = 21.6 - 12.7 = 8.9 mL Since 1 mL = 1 $cm^{3}$ Thus, 8.9 mL = 8.9 $cm^{3}$ Since Density = $\frac{Mass}{Volume}$ Thus Density = $\frac{33.42}{8.9}$ = 3.755 $\frac{g}{cm^{3}}$
