A sample of an unknown material appears to weigh 270 N in air and 165 N when immersed in alcohol of specific gravity 0.700.
(a) What is the volume of the material?
(b) What is the density of the material?

YOu know immersed, its bouyancy force is equal to the weight of the displaced medium; Archimedes discovered that. change specific gravity to density.
270165=densityalcohol*volumedisplaced*g
solve for volume displaced, duh, double duh, that is the volume
density= mass/volume= 270/g * 1/volume in kg/m^3
