Question
student measures 15.5 ml of a blue liquid in a graduated cylinder and 12.0 graduated cylinder. She then pours the red liquid into the graduated cylinder containing the blue liquid, and ml'of a red liquid in another the liquids mix. a) What color do you expect the mixture to have? b) What will the total volume of the mixture be? c) Will it be easy to separate the mixture into the red and blue liquid? Why or why not? Exercise 5: A student measures 10.5 ml of a blue liquid in a graduated cylinder and 5.2 ml of a red liquid in another graduated cylinder. She then pours the red liquid into the graduated cylinder containing the blue liquid, and the tiquids do NOT mix. Instead, the red liquid remains on top of the blue liquid. a) What causes the red liquid to remain on top of the blue liquid? b) Have you seen two liquids that do not mix before? What were they? What is the volume of the two liquids together after they were combined? Would you be able to easily separate the liquids in this case? How would you do that? c) d) a d= Exercise 6: The density of a substance is defined by the equation Where d stands for density, m stands for mass and v stands for volume. So if a sample "A" has 3.45 g of mass and 3.25 ml, we can obtain the density by dividing 3.45 g by 3.25 ml a) Obtain the density of sample "A" using the above values for mass and volume. The units should be g/ml". b) Another sample "B" has 4.56 ml and 5.49 g. What is its density? Show your calculation c) Which sample, "A" or "B", has the highest density?Explanation / Answer
you are mixing 15.5 ml of blue liquid
12 ml of red liquid
The solution will have a magenta-violet color but the blue color will be easier to identify because there is more of the blue solution
total volume of mixture : 15.5 + 12 = 27.5 ml
c) It wont be easy to separate since they have mixed , the molecules have some attraction forces among them.
5)
a) density, the solution with a lower density will remain at the top of mixture
b) Yes, oil and water
c) total volume = 10.5 + 5.2 = 15.7 ml
d) Yes you can separate them, you can use a funnel to remove the liquid at the bottom , just put the mixture in a funnel and wait until you see 2 different layers
6)
density = 3.45 / 3.25 = 1.061 g/ml
B) mass 5.49g
volume is 4.56
density = mass / volume = 5.49 / 4.56 = 1.204 g/ml
sample b has a higher density according to this values
