After the storm in February, New York City saw a total of 26 inches of snow, making 2021 the 8th most snowiest year. 13-inches (in.) of snow is equivalent to 1-inch of rain (per square foot). That is about 0.623 gallons (gal.) of water. The size of New York City including its boroughs is 302.6 square miles. This means that the total snowfall in 2021 has blanketed the Big Apple with 5,255,628,000 gallons of water!!!

Conversion Chart:
1 gal. = 3.78541 liters (L)
Kf of water = 1.86 °C/m
Density of water = 0.997 g/mL
Molar Mass of NaCl = 58.44 g/mol

1.) In order to depress the freezing point of water by at least 0.01 degrees Celsius (ºC), how many kilograms (kg) of salt is required to treat the entire city?
2.) Would you recommend increasing the amount of salt? Why or why not? (HINT: think molality)
Extra Credit: Convert the kilograms of salt to tons (tn.) (1 tn. = 907.185 kg)

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?
