Then ,$\text{1 pound}=\dfrac{1}{2.20}\text{ kilogram}$

$\Rightarrow\text{50 pounds}=\dfrac{1}{2.20}\times50\approx22.72text{ kilogram}$

Now, the dose of drug should be given to a 22.72 kilogram patient is given by :-

$22.72\times0.1=2.272g$

Since 1 grams = 1000 milligrams

$2.272\text{ g}=2,272\text{ mg}$
