Question

a mixture of 100g two liquids are mixed in the ratio 1:3 of their masses. If their

densities are 1.25gcm-3 and 0.6gcm-3. Find the density of the mixture.​

Answer 1

Answer:

Let the total mass of d

1

fluid be 3m and the volume is V

1

.

Let the total mass of d

2

fluid be 5m and the volume be V

2

.

So 3m=d

1

V

1

5m=d

2

V

2

Now when mixed the total mass m

t

=3m+5m=8m

and total volume is V=V

+V

Density of mixture d=
