Question

A metallic object of irregular shape displaces 21ml of water when it is immersed in a measuring cylinder containing water . If it's mass is 56.7g what is its density???

Answer 1

Answer:

Density = Mass/Volume

Here the object displaces 21 ml of water which is its volume or space occupied by the object and mass of object is 56.7 g

Hence d= 56.7/21 = 2.7 g(cm³)⁻¹

1 ml = 1 cubic centimeter
