Question
A liquid having a mass of 250 g fills a space of 1000 cc. Find the density of the liquid.
Solution
Given : Mass of a liquid M = 250 g
Volume V = l000cc
Density of the liquid D = ?
Density D= `("mass"("m"))/("volume"("v")) = (25cancel0)/(100cancel0) = 0.25 "g"//"cc"`
Solution: Density of the liquid = 0.25 g/cc
