Conversion to make my solution?

uming you are making a w/v percent solution, then 0.2% w/v means 0.2 gms/100mls or 2 gms/liter. Since the SnL is 3.6% saccharin, this mean each 1 gm packet has 0.036 gms of saccharine. You need 2 gms, so 2gms/0.036gm/pkg = 55.55 packages or about 56 packages of SnL per 1 liter of solution.
