Solution

Given,
Weight of the density bottle=30 g
Weight of density bottle + water=75 g
Weight of density bottle and liquid=65 g
Suppose V is the volume of the bottle.
Mass of water in the bottle=75-30=45 g
Density of water=Mass of water / Volume of water
1 g/cc=45/ V
Or V=45 cc
Thus, the volume of the bottle is 45 cc.
