one litre substances of densities 3 g/cc is mixed homogeneously of 3 litre af another density 2g/cc.find the density of mixture
Answers
Given : 1 litre substance of density 3 g/cc is mixed homogenously with 3 litre another substance of density 2g/cc.
To Find : the density of the mixture
Solution:
Density = mass / volume
1 litre substance of density 3 g/cc
1 litre = 1000 cc
Hence Mass = 3 * 1000 = 3 kg
3 litre another substance of density 2g/cc.
=> Mass = 3 * 2 * 1000 = 6 kg
Total Mass = 3 + 6 = 9 kg = 9000 g
Total Volume = 1 + 3 = 4 litre = 4000 cc
Density of mixture = 9000/4000 = 2.25 g/cc
the density of the mixture is 2.25 g/cc
