13. – 14. Differentiate between homogeneous and heterogeneous mixtures and give
an example of each.
Homogenous means the particles are evenly
spread out, you can’t see any different kinds of
particles in it. Iced tea, Kool Aid, salt water and
coffee are all examples
Heterogenous means the particles are unevenly
spread out, you can see any different kinds of
particles in it. Salad, Italian salad dressing, and
salsa are all examples.
Solve these problems. Show your work.
3.3 g/mL____You have a 50. mL bottle with 163 g of a green
15. ___
liquid. What is its density?
D = m/v
