Question no.4..
The volume of a 500g...

Answer 1

Density of packet= 500/350
                           =1.42 g/cm^3
This is more than the density of water so the packet will sink.
Mass of water displaced= density x volume
                                       = 500/350 x 350
                                       = 500 g
Bouyant force= volume x density x force of gravity.
                      = 350 x 500/350 x g/1000
                      = 500 x g
                      = 500 x 10
                     =5 N
