Question

The volume of a 500 gm sealed packet is 350 cm³. What will be the mass of the water displaced by this packet?(given that density of water = 1g/cm³)

• A. 50 gm
• B. 250 gm
• C. 300 gm
• D. 350 gm

Answer 1

The correct option is D

350 gm

Mass of packet = 500 g

Volume of packet = 350 cm³

Density of packet = Mass ÷ Volume = (500 / 350) g/cm³ = 1.43 g/cm³

The sealed packet will sink in the water as its density 1.43 g/cm³ is more than that of water.

The volume of water that will be displaced by the packet = 350 cm³

And mass of this displaced water = Volume x Density = 350 x 1 = 350 gm.
