The density of a liquid is 1.87g/mL and a volume of 5 mL. What is the mass of the liquid?
9.35g
density
What is the measure of the amount of mass in a given volume of a substance.
Water - displacement
What process do you use to find the volume of an irregular object?
How do you find the density of an irregular object?
Use a balance to find the mass.
Use a graduated cylinder to find the volume (water-displacement).
Divide the mass by the volume.
Which lab tool would you need to find the volume of an irregular object?
graduated cylinder
A substance has a mass of 2.5g and a density is 0.5 g/mL. How does this compare to water?
Based on the density of 0.5 g/mL, this substance is less dense than water. Water is 1 g/mL, which is twice as dense as this substance.
