Question

Three liquids of densities d, 2d, and 3d are mixed in equal volumes. Then the density of the mixture is:
(a) d (b) 2d (c) 3d (d) 5d
@Mathematics

Answer 1

2d

Answer 2

Can you explain how?

Answer 3

d=m/V

m1=dV
m2=2dV
m3=3dV

then d(mixture)=(m1+m2+m3)/(V+V+V)=(6dV)/(3V)=2

Answer 4

Thanks

Answer 5

welcome

Answer 6

the answer must be 2d not 2:)
