I have a stock solution of 550mg/ml that I want to dilute to 50ug/ml
How would I do this?
Measure out any convenient amount, say 1 mL
Add solvent to make up total of 11000 times that volume, ie 11 liters total. It will be 1/11000 the strength, 50 µg/mL.

solution:
1 µg/mL= 0.001 mg/ml
50 µg/mL = 0.05 mg/ml
stock sol is 550mg/ml,
so take 5 ml from stock soln, and dilute it upto 100 ml. ( u will get 50 µg/mL dilution)

Thanks for coming on and helping. Here is where you went wrong:
The original stock solution is VERY concentrated: 550,000ppm.
If you take 5mL, you have 2750mg, which you are diluting to 100mL. This gives a resulting conc of 27500mg/L or 27500ppm. (27.5mg/mL). Still quite concentrated.
V1: The volume of solvent that you'll need to add
C1: The concentration of the initial stock solution
V2: The final volume you want
C2: The concentration you want in your final volume
V1: The volume of solvent that you'll need to add
C1: The concentration of the initial stock solution
V2: The final volume you want

I think V1 is mislabelled and is the volume of stock solution required.
I have a stock solution of 100mg/ml,then how can i prepare 2mg/ml.
Dilute 50:1. Measure out any convenient amount, add solvent to dilut to total volume 50X that amount, for example 1 mL, dilute to 50 mL (requires about 49 mL of solvent). Volumes are not EXACTLY additive so dilute to measured final volume.
Good morning,I trust you're all well. I have a quick question. I have a Gro/MGSA standard of concentration 1ug/ml. I need to dilute this standard from 1ng/ml to zero in diluent. I know 1ug.ml = 1000pg/ml...how do I go about this please? Thanks

1 µg = 1000 ng or 1 million pg.
To dilute any concentration to ZERO requires an infinite amount of solvent. Good luck.
