Density Flashcards
1
Q
What is density?
A
How much mass is packed in a measured volume.
2
Q
Density = ?
A
mass/volume
For liquids - g/cm3
For solids - g/mL
3
Q
What happens if substances have a density that is equal to or less than water?
A
The substance will float.
4
Q
How can we measure density volume of an irregular shape?
A
Added volume - Initial volume = Volume of shape
- using a measuring cylinder and water
- read from bottom of meniscus
5
Q
Formula for density?
A
D = M/V - g/cm3 or g/mL
V = M/D - cm3
M - D x V - g
