:




Therefore, the solution is 
Answer:
The ML draw up = 1.2 ML
Step-by-step explanation:
we are told that concentration of Ceftriaxone = 1g/ 9.6ML
This means that:
9.6 ML contains 1g ceftriaxone
1g = 9.6 ML
note also that 1g = 1000mg
∴ 1000mg = 9.6 ML
∴ 1mg = (9.6 ÷ 1000) ML
1mg = 0.0096 ML
∴ 125 mg = 125 × 0.0096 = 1.2 ML
Therefore, 1.2 ML will be drawn up
