Homework Statement


In a mixture of 100 gm , 2 liquids are mixed in ratio 1:3 of their masses . If densities of liquids are 1.25gm/cc and 0.6gm/cc , find the density of mixture.


Homework Equations


D = mass/Volume


The Attempt at a Solution


mass = 100g
let m1 = x , m2 = 3x
d1 = 1.25 gm/cc , d2 = 0.6gm/cc
mass = m1+m2
100= 4x
100/4 = x
m1 = 25, m2 = 75
V1= 25/125*100 = 20cm3
V2 = 75/6*10 = 125cm3
d = mass/volume
= 100/145 = 20/29 = 0.6gm/cc

is that ^^ correct?
