Question

An irrelgular object with a mass of 118g displaces 25ml of water when placed in a graduated cylinder. What is the density

Answer 1

Density = Mass of Object / Volume of water displaced.

The volume of water displaced is the same as the volume of the object.

Density = 118 g / 25 ml

= 4.72 g/ml

But 1 liter = 1000 cm³
1 mL = 1 cm³

Density = 4.72 g/ml = 4.72 g/cm³
