Answer
A total of 3 tablets should be given to the patient.
Work Step by Step
1. Identify the conversion factors.
- We need to convert from "L" to "gallons".
Looking at the table 2.7 (Page 38), we can see that:
$1$ $g = 1000$ $mg$
And the exercise gives: $1$ tablet = $8$ $mg$
2. Calculate the number of tablets, using the conversion factors:
$0.024g \times \frac{1000mg}{1g} \times \frac{1tablet}{8mg} = 3$ $tablets$
The number of tablets is an integer with only 1 SF, so we don't have to change the number of significant figures.
