Once again, 1000. We divide by 1000 because we want to go from grams to kilograms. So 1 gram over ML, which is our density times 800 ML over 1000, gives us the MLS cancel grams becomes kilogram because we're dividing by 1000 and that gets us zero 8 solid. So now we have our Molarity, namely zero point 71 moles divided by 0.8
kg, so a bit less than one. So we go to our final step. In our final step we simply write the formulas for the change in boiling point and changing freezing point when we add a salute.
