I have been asked to calculate the amount of Uric acid  "per unit body-weight" in each age class.

Weight (g)   Age (days)     Concentration ( mg/mL)
0.22              4                 0.092
0.23              9                 0.103

Am i right to assume that its  0.092/0.22 = 0.418 ?
The units are confusing me for some reason. Is " per unit body-weight" mg/Kg? If yes, is the answer 0.418 mg/Kg for the age 4 one.

Thank for considering.

Look at your calculation in terms of units you have mg mL^-1/g = mg mL^-1g^-1

If you want Kg as the unit body weight you have to convert the g to kg

As long a you define what your unit weight is it doesn't matter whether its kg or g
