Question

A substance of density 4g/cm3 causes 60g of turpentine of density 0.8g/cm3 to overflow from a displacement vessel. What is the mass of the substance?

Answer 1

Let m mass of the substance overflow from a displacement vessel.

given,

density of substance = 4g/cm³

density of turpentine = 0.8 g/cm³

mass of turpentine = 60g

we know formula of displacement vessel.

displacement = light weight + dead weight

if displacement = 0

then, light weight = dead weight

so, mass of substance = mass of turpentine

4 × m = 0.8 × 60

m = 12g

hence, weight of substance is 12g.
