Practicing Density Calculations: A 4.80 gram piece of magnesium displaces 2.76 mL of water when it’s placed in a graduated cylinder . What is the density of the magnesium?

1.74 g/mL

Explanation:

Step 1: Given data

Mass of magnesium: 4.80 g

Volume of water displaced: 2.76 mL

Step 2: Calculate the volume of the piece of magnesium

The volume of the piece of magnesium is equal to the volume of water displaced in the graduated cylinder.

Step 3: Calculate the density of magnesium

The density of magnesium is equal to its mass divided by its volume.

ρ = m / V

ρ = 4.80 g / 2.76 mL

ρ = 1.74 g/mL
