Calculate the concentration of a 220 g solution of calcium chloride (CaCl2) that has a volume of 11 L

The concentration of the solution is 0.18 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in L

moles of =

Now put all the given values in the formula of molality, we get

Therefore, the concentration of the solution is 0.18 M

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
