Answer
$$8 \space tablets$$
Work Step by Step
1. Identify the equalities and conversion factors that we will use to solve this problem:
$$1.0 \space g \space tetracycline = 6 \space hours$$ $$1 \space day = 24 \space hours$$ $$1 \space tablet = 500 \space mg \space tetracycline$$ $$1000 \space mg = 1 \space g$$* Check Table 2.7 (Page 38)
2. Solve the problem using multiple conversion factors:
$$1 \space day \times \frac{24 \space hours}{1 \space day} \times \frac{1.0 \space g \space tetracycline}{6 \space hours} \times \frac{1000 \space mg}{1 \space g} \times \frac{1 \space tablet}{500 \space mg \space tetracycline} = 8 \space tablets$$
