Question

11mg of cyanide per kilogram of body weight is lethal for 50% of domestic chickens. How many grams per kilogram of body weight is a lethal dose for 50% of domestic chickens?

Answer 1

`0.033g`

Step-by-step explanation:

Hello,

In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

`11mg\longrightarrow 1kg\\\\x\ \ \ \ \ \ \longrightarrow 3kg`

Thus, we obtain:

`x=(3kg*11mg)/(1kg)\\ \\x=33mg`

That in grams is:

`=33mg*(1g)/(1000mg) \\\\=0.033g`

Regards.
