Temperature is -3 degree Celsius. 10 kg of snow is covering the driveway. How much of salt would you need to melt the snow on the driveway. (freezing point is 0 degree Celsius, I=2.1)?Please provide solution with all steps and also I made up the given numbers so they are not exact so the final answer could be a value that doesn't make sense but it is the steps I need to know?
