The volume of a 500g sealed packet is 350 cm3. Its density is 1.4g/cm3. What will be the mass of the water displaced by this packet? (density of water =1g/cm3)
Volume of water displaced = 350 cm3
Since, its density is greater than water, it will sink in water and will displace an equal volume of water.
Thus, mass of water displaced = volume × density = 350 x 1 = 350 g
