Question

When two liquids of same volumes but different densities are mixed then new density is

Answer 1

Let the volume of both the liquids be V

P1 and P2 be the density of both liquids

According to formula volume = mass / density

V+V= mass(assume very less)/P1+mass(assumed very less)/P2

2V = P1+P2/P1*P2

V= P1+P2/2P1*P2

NOW USING 1

DENSITY = MASS/VOLUME

DENSITY = 1/P1+P2/2P1*P2

DENSITY = 2P1*P2/P1+P2
