Calculate the concentration (% W/V) of NaCl solution that was made by dissolving 15.0 g of sodium chloride in enough water to make 300.0 mL of solution. Okay the answer is 5.00%....however I keep getting 0.0500%....Why? and which one is the correct answer? Thanks for your help! :)

  • Chemistry -

    Go back and look at my answer. I showed it by steps. You are dividing 5/100 to get 0.05 but that isn't the definition. 5% w/v means 5 g/100 so in 300 mL you would have 15.0 grams.
