Question

if two liquids of same mass but density P1 and P2 are mixed then the density would be ​

Answer 1

Answer:

The density of the mixture will equate to the mass of the mixture divided by the volume of the mixture, i.e.

Pmix=MmixVmix

If the mass of each substance is m , then (assuming that the mixing does not lead to a chemical reaction that, say, produces a gas), then Mmix=2m

What is Vmix ? Well, as has already been mentioned by , adding a volume V1 of one substance to a volume V2 of another substance does not always result in a mixture with a volume equal to V1+V2. If this is the case with your two substances, then we can go no further than saying

Pmix=2mVmix

But what is there is no change in volume?

Well, we know that P1=mV1 , so V1=mP1

Likewise, V2=mP2

Thus Vmix=mP1+mP2=mP1+P2P1.P2

Thus Pmix=2mm(P1+P2)P1.P2=2m.P1.P2m(P1+P2)=2P1.P2P1+P2
