Question

Two substances of densities P1 and P2 are mixed in equal volume and the relative density of mixture is 4. When they are mixed in equal masses, the relative density of the mixture is 3. The values of P1 and P2 are..

Answer 1

Answer:

p1=6 and p2=2

Explanation:

We know that:

when 2 liquids mixed in equal volume their net density is p1+p2/2 so we deduce that

p1+p2=8----1)

Also, when 2 liquids are mixed in equal masses their net density is 2p1p2/p1+p2

as p1+p2=8

we get that 2p1p2=8*3=24

so p1p2=12
as p1+p2=8 and p1p2=12 we see that 6,2 are the values satisfying the eqn therefore p1=6 and p2=2

hope that helped pls mark as brainliest!
