Consider two jars. One jar contains 100 blue spheres, and the other jar contains 25 each of red, blue, green, and yellow colors mixed together.
• a. If you were to remove 30 blue spheres from the jar containing just the blue spheres, what would be total mass of spheres left in the jar? (Note that the masses of the spheres are given in Part 2.)blue sphere = 4.0g 4.0g x 100 =400.0gm4.0g x 30 = 120gm400.0 - 120 = 280.0gm
• b. If you were to remove 30 spheres from the jar containing the mixture (assume you get a representative distribution of colors), what would be the total mass of spheres left in the jar?
