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 :

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

[tex]\\ \tt\longmapsto Density=\dfrac{Mass}{Volume}[/tex]

[tex]\\ \tt\longmapsto Density=\dfrac{20.3}{10}[/tex]

[tex]\\ \tt\longmapsto Density=203g/mL[/tex]
