$ 2 \mathrm{mEq}: 1 \mathrm{~mL}=40 \mathrm{mEq}: x \mathrm{~mL} $ 
$ 2 x=40 $ 
$ x=20 \mathrm{~mL} $

Proof: $ 2 \times 20=40 $
$ \quad $$ \quad $ $ 1 \times 40=40 $ b. $ 133 \mathrm{~mL} $

Know $ \quad $$ \quad $$ \quad $$ \quad $ Want to Know

$\begin{array}{l}
9 x=20 \times 60=1200 \
9 x=1200 \
x=133.33=133 \mathrm{~mL} \text { per hr }
\end{array}$

Proof: $ 20 \times 60=1200 $
$ \quad $$ \quad $$ \quad $$9 \times 133.33=1199.9$

$ 250, \theta \theta \theta $ units : $ 1 \mathrm{~mL}=250, \theta \theta \theta $ units : $ x \mathrm{~mL} $ 
$ 250 x=1250=250 $
$ x=1 \mathrm{~mL} $

Proof $ 1 \times 250=250 $
$  \quad $$  \quad $$ 250 \times 1=250 $ The 1 mL concentration is recommended as penicillin can be irritating in a concentrated form.
