If the soda you are drinking contains 0.5% by mass sodium benzoate as a preservative. What approximate mass of sodium benzoate is contained in 1.00 L of the solution assuming that the density of the soda is 1.00 g/mL(the approximate density of water)?

    0.5% w/w means 0.5 g sodium benzoate in 100 g soln. Therefore, in 1000 g soln (1000 mL with a density of 1.00 g/mL), there will be 5 g sodium benzoate (0.5g x 1000/100), right?
