it is 6%
by: Van

60g/1000ml*100%=6%.

and "how many ml of diluent need to add to 2.5g to make solution with 250mg/ml" is the second qs that you want to ask???

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 mL
6000=100X
6 = X
therefore you have a 6% solution

Your 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 = 250/1
2500 = 250X
10 = X
therefore you need to add 10 mL
