Density Calculation Practice (CHEM 1405)

Solve each of the equations listed below. Use the following equations to help you:

$LaTeX: D=\frac{m}{V}$ $D=\frac{m}{V}$ mass = grams volume = cm³, mL

$LaTeX: V=l\times w\times h$ $V=l\times w\times h$

1) What is the density of an object with a mass of 60 g and a volume of 2 cm³?

2) You are given the following information: mass = 48 g; volume = 24 mL. What is the density of this substance?

3) If you have a rectangular gold brick that is 2 cm by 3 cm by 4 cm and has a mass of 48 g, what is its density?

4) Bob, who weights 150 pounds, found a rock. What is the density of a rock if its mass is 36 g and its volume is 12 mL?

5) If a block of wood has a density of 0.6 g/cm³ and a mass of 120 g, what is its volume?

6) What is the mass of an object that has a volume of 34 cm³ and a density of 6 g/cm³?

7) What is the density of a 75 g block of wood measuring 12cm x 8 cm x 9 cm?

8) What is the density of a 22 kg boy who’s volume is 6,400 mL?

9) What is the mass of 300 mL of a liquid with a density of 2.3 g/mL?

10) What is the volume of a substance with a mass of 0.35 g and a density of 0.9 g/cc?
