Given the concentration,
![500*10^{-6} g = 1ml\\1*10^{-6}g =\frac{1}{500} ml\\180*10^{-6} g=(\frac{1}{500} *180)ml\\180micrograms = 0.36ml](https://tex.z-dn.net/?f=500%2A10%5E%7B-6%7D%20g%20%3D%201ml%5C%5C1%2A10%5E%7B-6%7Dg%20%3D%5Cfrac%7B1%7D%7B500%7D%20ml%5C%5C180%2A10%5E%7B-6%7D%20g%3D%28%5Cfrac%7B1%7D%7B500%7D%20%2A180%29ml%5C%5C180micrograms%20%3D%200.36ml)
