in one of the routine analyses, dr entropy found that the concentration of phosphate had increased from 0.0090 mg/l to 0.220 mg/l. this will require a lengthy investigation and detailed report into the causes. being the master of disorder, he considers an act of serious scientific misconduct - diluting the sample to reduce phosphate concentration to the maximum allowable level of 0.100 mg/l, and hoping that no-one notices.

if the volume of the original sample with concentration 0.220 mg/l is 10.0 ml, what should be the final volume of solution in order to dilute it to 0.100 mg/l?

Write the empirical chemical formula of calcium with a mass percent of 38.8, phosphorus with a mass percent of 20.0, and oxygen with a mass percent of 41.3.

Actual ingredients of lab (the cookies i am actually making) 1/2 cup sugar 1/2 cup brown sugar 1 1/3 stick margarine 1 egg 1/2 tsp salt 1 tsp vanilla 1/2 tsp baking soda 1 1/2 cup flour 1 1/3 cup chocolate chip can you answer the questions below ? discussion 1. suppose you are given the following amounts of ingredients: 1 dozen eggs 24 tsp. of vanilla 1 lb. (82 tsp.) of salt 1 lb. (84 tsp.) of baking soda 3 cups of chocolate chips 5 lb. (11 cups) of sugar 2 lb. (4 cups) of brown sugar 1 lb. (4 sticks) of margarine a. for each ingredient, calculate how many cookies could be prepared if all of that ingredient were consumed. (for example, the recipe shows that using 1 egg- with the right amounts of the other ingredients- yields 24 cookies. how many cookies can you make if the recipe is increased proportionately for 12 eggs? ) b. to determine the limiting reactant for the new ingredients list, identify which ingredient will result in the fewest number of cookies. c. what is the maximum number of cookies that can be produced from the new amounts of ingredients?

What happens when the temperature of a solution increases?
