a) A graduated cylinder with 18 ml of water will contain18gm of water, which equals one mole of water molecules. If each ofthese water molecules were enlarged to the the size of a billiardball (2.25 inches in diameter ) were stacked side-by-side on afootball field using only the inbounds area (120.00 yards by 60.00yards), how high would a mole of billiard balls reach inKilometers? Assume that all billiard balls are identical. Show allcalculations.
b) Traveling at the speed of light - how long would it take,in years, to reah the top the pile (of billiard balls)?. Show allcalculations.
c) The ball each have a mass of 15.00 ounces each. If 16ounces equals 454 grams, what is the density of the rectangularprism that encloses the ball?. Show all calculation.
