the addition of 50 g of salt to a sample of pure water causes its freezing point to be reduced from 0.0 degrees Celsius to -3.15 degrees Celsius. determine how many degrees the freezing point dropped for every 10 g of salt added.

Thank ya, randomchik.

    Wait, never mind. It is 0.63, right? Well thanks anyways. ☠randomchika☠

    assuming it's a linear relationship, then the change is -3.15°/50g = -0.63°/10g
