Answer to Question #19783 in Physical Chemistry for ozen cemal
when equal volumes of liquid AandB are mixed,a solution with a density of 1.2g/mL is obtained.when equal masses of these liquids are mixed the density of the mixture is found to be o.9g/mL.find the density of each kliquid.
d = (d1+d2)/2
d1 = m1/v1 v1 = m1/d1 d2 = m2/v2 v2 = m2/d2
when v1 = v2, d = (d1+d2)/2
when m1 = m2 d = 2m1/(m1/d1+m2/d2) = 2m1/((m1d2+m2d1)/d1d2) = 2d1d2/d1+d2
