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