Question

If the density of ocean water at a depth of 1.00 x 10^4 m is 1.071 g/mL and if 27.0 g of water at that depth contains 197 mg of potassium chloride, what is the molarity of potassium chloride in the sample?

M = mols/L
How many mols KCl are there? mols = grams/molar mass = ?
How2 many L are there? That's mass H2O = volume H2O x density H2O. Solve for volume in mL and convert to L.
