Explanation:

Step1: Convert lbs to kg

$185\ \text{lb} \times \frac{1\ \text{kg}}{2.205\ \text{lb}} \approx 83.90\ \text{kg}$

Step2: Calculate dose in mg

$83.90\ \text{kg} \times 7.93\ \frac{\text{mg}}{\text{kg}} \approx 665.33\ \text{mg}$

Step3: Convert mg to g

$665.33\ \text{mg} \times \frac{1\ \text{g}}{1000\ \text{mg}} = 0.665\ \text{g}$

Answer:

$0.665$ g
