Answer:
Density of mixture is 7.0 g/.
Step-by-step explanation:
Density of mixture = density of water in the mixture + density of oil in the mixture
Given: water and oil were mixed in a ratio 3:5
density of water is 1.0 g/ and that of oil is 0.8 g/
.
Then,
density of water in the mixture = 3 x 1.0 g/
= 3.0 g/
Density of the volume of water in the mixture is 3.0 g/.
density of oil in the mixture = 5 x 0.8 g/
= 4.0 g/
Density of oil in the mixture is 3.0 g/.
So that,
Density of mixture = 3.0 + 4.0
= 7.0
Density of mixture is 7.0 g/.
