Answer
$$1800 \space mg \space ampicillin$$
Work Step by Step
1. Identify the equalities and conversion factors that we will use to solve this problem:
$$115 \space mg \space ampicillin = 1 \space kg \space of \space body \space weight$$ $$1 \space kg = 2.20 \space lb*$$ * Check Table 2.7 (Page 38)
2. Solve the problem using multiple conversion factors:
$$34 \space lb \space body \space weight \times \frac{1 \space kg}{2.20 \space lb} \times \frac{115 \space mg \space ampicillin}{1 \space kg \space body \space weight} = 1777.27 \space mg \space ampicillin$$
- Rounding off to 2 significant figures:
$$1800 \space mg \space ampicillin$$
