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

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
