To prevent bacterial infection the doctor order 67 of amoxicillin per day for 11 days if each tab contains 150 mg of amoxicillin how many ounces of the medication are given in 11 days express your answer using two significant figures

Answer 1

First: 6 Tables of amoxicilin per day

Second: The patient have to follow the treatment for 11 day

Third: Each table of amoxicilin contains 150 mg

1. 6 tables per day:

If:

$\begin{gathered} 1Table\rightarrow150mg \\ 6Tables\rightarrow x \end{gathered}$

Where x is te quantity in mg per day.

$x=150mg*6=900mg$

Now, the treatment is for 11 day:

$11days=900*11=9900mg$

The quantity of amoxicilin in 11 days is : 9900 mg.

Now, we have to convert mg to Oz:

We know that: 1 gram is equal to 0.035274 Oz. Therefore:

$\begin{gathered} 9900mg*\frac{1g}{1000mg}*\frac{0.035274\text{ O}z}{1g}=0.3492126Oz\approx0.35\text{ }Oz \\ \end{gathered}$

Answer: The medication of amoxicilin in 11 days is: 0.35 Ounces.
