RP5 - Density - Part 3: Calculating the density of a liquid. Flashcards
1
Q
Outline the basic steps of the practical.
A
- Measure the mass of the empty measuring cylinder
- Pour around 100cm^3 of liquid into the cylinder and record the volume
- Measure the mass of the cylinder with liquid in, and subtract the cylinder’s mass to calculate the mass of liquid.
- Calculate density from mass and volume

Q
How does the density of solids and liquids compare?
A
In general, solids are more dense than liquids since their particles are more tightly packed together meaning there is more mass per unit volume.
