Two miscible liquids of densities 1.2gm/...

Two miscible liquids of densities `1.2gm//cm` and `1.4gm//cm` aer mixed with a proportion ratio of their volumes equal to 2.5: what is the density of redulting liquid?

Text Solution

Verified by Experts

` rho = (rho_(1)v_(1)+rho_(2)v_(2))/(v_(1)+v_(2)) rArr rho = (rho_(1)(v_(1))/(v_(2)) + rho_(2))/(v_(1)/(v_(2))+1)`
` rArr rho = ((1.2) (3//5) +1.4)/((3//5)+1) = (3.6 + 7 )/8 rho = 1.325`
