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)
2. The slopes of the lines in graph 1 can be interpreted as a useful quantity around the lab if you were working with water or one of these solutions. Explain the significance of the slope and how it might be used around the lab. Hint: look at the units and remember when a line is drawn it represents a sort of average as it places about half of the data above and below it due to random errors.
A high-‐speed chase captured on a surveillance camera showed the suspect running a red light at an The suspect vehicle collided with a vehicle that had just turned into the path of his car. The tape shows that it took the car 0.546 s to cross the intersection, which was measured to be 41.2 ft. The posted speed limit was 25 mph. Determine whether the suspect was speeding at the moment he collided with the second vehicle.
