Question

Calculate the density of two matters of density P1 and P2 if mixed in same mass?

Answer 1

Answer:

2(p1*p2)/m(p1+p2)

Explanation:

Pmix=Mmix/Vmix

if the mass of each substance is m the, Mmix=2m

adding a volumeV1 of one substance to a volume V2 of other substance does not always result in a mixture with a volume equal to V1+V2

Pmix=2m/Vmix

P1=m/V1

V1=m/P1

V2=m/P2

Vmix=m/p1=m/p2

       =m(P1+P2)/P1*P2

Pmix=2m/m(p1+p2)/p1*p2

     =2m*p1*p2/m(p1+p2)

  =2(p1*p2)/p1+p2  ANS
