Answer:
[tex]\large \boxed{32}[/tex]
Explanation:
[tex]\text{Dosage rate} = \dfrac{\text{2.0 g}}{\text{6 h}}[/tex]
We must convert this measurement to units of "tablets per day".
1. Convert grams to milligrams
[tex]\text{Mass} = \text{2.0 g} \times \dfrac{\text{1000 mg}}{\text{1 g}} = \text{2000 mg}[/tex]
2. Convert milligrams to tablets
[tex]\text{No. of tablets} = \text{2000 mg} \times \dfrac{\text{1 tablet}}{\text{250 mg}} = \text{8.0 tablets}[/tex]
3. Convert hours to days
[tex]\text{Time} = \text{6 h} \times \dfrac{\text{1 da}}{\text{24 h}} = \text{ 0.25 da}[/tex]
4. Calculate the tablets per day
[tex]\dfrac{\text{2.0 g}}{\text{6 h}} = \dfrac{\text{8.0 tablets}}{\text{0.25 da}} = \textbf{32 tablets per day}\\\\\text{The patient must take $\large \boxed{\textbf{32 tablets per day}}$}[/tex]
