Question

1) 50.0 mL of water is measured out in a graduated cylinder. A rock with the mass of

20.3 g is dropped into the cylinder. The water level goes up to 60 mL.
A) What is the volume of the rock?
B) What is its density?

Answer 1

• Volume=Rised height-Measured height=60-50=10mL
• Mass=20.3g

`\\ \tt\longmapsto Density=(Mass)/(Volume)`

`\\ \tt\longmapsto Density=(20.3)/(10)`

`\\ \tt\longmapsto Density=203g/mL`
