So now we have the top component of our mortality. Let's find the bottom. Remember, it's moles of solute divided by kilogram of solvent. To find the kilograms of our solvent, we have to use the density of water, the fact that we have 800. Then we have to divide by a thousand because we want to go from grams to kilograms. So our density of water times milliliters of solvent divided by 1000.
