Question

Calculating the density of each object with the correct amount of sig. figs. and predict if it will sink or float in water. A wooden object has a density of 12 g/mL and a volume of 7 mL. What is the mass of this object? A lab measures a piece of crumpled aluminum and finds its mass to be 14.3g and itʼs volume to be 5.26mL. Later on, they have a second piece of crumpled aluminum, which has a mass of 12.3g. Whatʼs the volume of the second piece?

1. Calculating the density of each object with the correct amount of sig. figs. and predict if it will sink or
float in water.
a. mass = 12.1g volume = 4.1 ml D= ?
b. mass = 823 g volume = ? D= 3.3 g/mL
Mass
Density | Vol
c. mass = ? volume = 8.23 mL D= 2.4 g/cm? d. mass = 0.233g volume = 12.3 mL D=?
