Jarvis is conducting an experiment to determine the amount of magnesium hydroxide that will precipitate out of an aqueous solution of 1 quart of water, 1 teaspoon of epsom salt, and 2 teaspoons of ammonia. Both of the compounds will dissolve in water.

Ammonia contains ammonium hydroxide, and epsom salt is magnesium sulfate. Mixing ammonia and epsom salt causes a reaction which produces magnesium hydroxide as one of the products. The magnesium hydroxide is a white substance that is insoluble in water. Within a few minutes, a white precipitate (magnesium hydroxide) will settle to the bottom of the jar.

Jarvis ran the experiment nine different times and recorded his measurements below.

What is the median amount of precipitate from the experiment?
