What volume of alcohol is displaced by a cork of mass 4.2g which floats in it is how much?
according to the principle of floatation
weight of the water displaced = weight of substance or object
= m x g = (4.2 x 10) = 42 N
VOLUME OF CORK = mass/density = 4.2/0.24 = 17.5 m3
as volume is also same as the liquid displaced.
therefore, volume of water displaced = 17.5 m3
