 Dec 21, 2010 answers by: Anonymous If you have 60g in 1000 mL you need to know how many grams are in 100 mL to find the percentage.60/1000 = X/100 mL6000=100X6 = Xtherefore you have a 6% solutionYour solution is 250mg/mL and you want to add 2.5 g to the IV bag. First you need to change your g to mg so you multiply 2.5 by 1000 and you get 2500 mg.If you have 250mg in 1 mL and you need to find how many mL you will need for 2500 mg.2500/X = 250/12500 = 250X10 = Xtherefore you need to add 10 mL
