The relationship between density, mass, and volume is given by:
[tex]\text{volume}=\frac{\text{mass}}{\text{density}}[/tex]Given parameters:
mass = 55.0g
density = 0.889 gcm^-3
The volume can be calculated as follow:
[tex]volume=\frac{55g}{0.889\text{gcm}^{-3}_{^{^{^{}}}}}[/tex]Hence, the volume is
[tex]\text{volume}=61.9g[/tex]Volume = 61.9 g (to 3 significant figure)
