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!!! onversion 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 Answer the following: 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)
