The volume of 500 g sealed packet is 350 cm3. Will the packet float or sink in water if the density of water is 1 g cm-3? What will be the mass of the water displaced by this packet?

Here, mass of packet, M – 500 g volume of the packet, V = 350 cm3 Clearly, density of packet,
d = \(\frac{M}{V}\) = \(\frac{500}{350}\) = \(1.428 g cm^{-3}\)
Since the density of packet is more than density of water, the packet will sink. As the packet is fully submerged in water, mass of water displaced by the packet = volume of the packet x density of water = 350 cm3 × 1 g cm-3 = 350 g
