Answer:
1.2 grams.
Explanation:
We have been given that an oral concentrate of sertraline hydro-chloride (Zoloft) contains 20 mg/mL of the drug.
First of all, we will find number of mg in 60 mL container of the concentrate as:
![\frac{\text{20 mg}}{\text{ml}}* \text{60 ml}](https://img.qammunity.org/2020/formulas/mathematics/college/e5i4j3vf9zq4kai9pct6rr40m8n5cchdzh.png)
![\text{20 mg}* 60](https://img.qammunity.org/2020/formulas/mathematics/college/s3wwh9tr7r8i10lxpreof2ram3nvl7o3rb.png)
![\text{1200 mg}](https://img.qammunity.org/2020/formulas/mathematics/college/sqpsyqgporvovog2fmqscoi1e3okzjra50.png)
We know 1 gram equals 1000 mg.
![\text{1200 mg}* \frac{\text{1 gram}}{\text{1000 mg}}](https://img.qammunity.org/2020/formulas/mathematics/college/vkst4vqubvon6fsfftwe8o4poo8sxu04wa.png)
![1.2*\text{1 gram}](https://img.qammunity.org/2020/formulas/mathematics/college/pms054h4zzftwyarb5stb1haft4gaq5yjc.png)
![1.2\text{ grams}](https://img.qammunity.org/2020/formulas/mathematics/college/huq6jbjzqnvtogq3j6pky3moq2rj0rctbn.png)
Therefore, 1.2 grams of sertraline hydrochloride are in each 60-mL container of the concentrate.
