Question

11mg of cyanide per kilogram of body weight is lethal for 50% of domestic chickens. If a chicken weighs 3kg, how many grams of cyanide would it need to ingest to kill 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\\\\?\ \ \ \ \ \ \longrightarrow 3kg`

Thus, we obtain:

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

That in grams is:

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

Regards.
