2.326 mg/mL means, the solution contains 2.326 mg of drug in each 1 mL. In order to express the ratio strength, we must keep the numerator in gram unit, also, the numerator should be equal to 1.
Since 1000 mg equals 1 g, we can write 2.326 mg as 0.002 g. Thus, for this solution, we can write:
`(0.002326\quad g)/(1\quad mL)=((0.002326/0.002326) \quad g)/((1/0.002326) \quad mL)`
`=(1\quad g)/(430\quad mL)`.
This is equivalent to 1 : 430. Answer.
