Question
A sample of metal weights 210 grams in air, 180 grams in water and 120 grams in an unknown liquid. Then : -
Options
A.the density of metal is 3 g/cm3
B.the density of metal is 7 g/cm3
C.density of metal is 4 times the density of the unknown liquid
D.the metal will float in water
Solution
Density of metal = 
= 7g/cm3
density of liquid =
= 3g/cm3
= 7g/cm3density of liquid =
= 3g/cm3Create a free account to view solution
