Which.i think its the answer
Answer:

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:

Thus, we obtain:

That in grams is:

I would say detailed drawing, but it is up to you
The boiling point of the calcium chloride CaCl2 solution will be higher than that of the boiling point of the sodium chloride NaCl solution, because more molecules are present in the CaCl2 solution since CaCl2 dissociates into three ions while NaCl only dissociates into two ions.
The volume shown in the graduated cylinder according to the image would 28 mL. Thus, the correct option would be C.
In the cylinder, the top of the liquid formed a concave meniscus with the walls of the cylinder. Thus, the bottom of the meniscus would be read as this is the normal rule.
The rule is such that for liquids that form concave meniscus with the walls of cylinders, the bottom of the meniscus is read while it is the top of the meniscus for liquids that form convex meniscus with the walls of cylinders.
Hence, looking at the image, the bottom of the concave is on the 28 mL mark on the cylinder.
