A 205 mL sample of ocean water is found to contain 7.2 g of NaCl, what is the molarity of the solution? (The problem also says, with respect to NaCl?) Ok, now, what do they mean with respect to NaCl? What is it usually in respect to? Anyways is this the correct way to do this? Recognize that NaCl is the solute, and the ocean water is the solution, then, you convert the 205 mL of ocean water to Liters and also you have to convert the 7.2 g of NaCl to mL, then L to add it with the ocean water because molarity is moles of solute divided by Liters of total solution isn't it? And then you just divide the solute converted into moles into that to determine the molarity?
