Answer:
0.25 ml
Step-by-step explanation:
It is given that,
Dosage of medicine = 20 mg
The medicine has a concentration of 80 mg/ml
We need to find how much medication will the patient receive. It can be calculated as follows :
![\text{Dosage}=(20\ mg)/(80\ mg/ml)\\\\=(20)/(80)\ \text{ml}\\\\=0.25\ \text{ml}](https://img.qammunity.org/2021/formulas/health/high-school/k6ebsm7bbf4z9m1tau17wcpt753rimjgm4.png)
So, the patient will receive 0.25 ml. Hence, the correct option is (a).
