During a lab activity a group of students was instructed to determine the density of a rock. Steps Use the balance to determine the mass of the rock. Use water displacement to determine the volume of the rock. Put 50 milliliters of water in the graduated cylinder, drop the rock in and measure the increase in the volume of the water. This will be the volume of the rock. Use the formula D=MV to calculate the density of the rock. Results Mass of the rock = 6.4 grams Volume of the rock = 0.5 mL Density = 6.40.5 = 12.8 g/mL Were the students measuring a physical property or a chemical property of the rock?
