Calculate the freezing point of a 2.6-molal aqueous sucrose solution. the freezing point depression constant for water is 1.86 degrees c/molal.

a.) 4.8 °c
b.) 1.4 °c
c.) -1.4 °c
d.) -4.8 °c

D.) -4.8 °C

Explanation:

The formula used for depression in freezing point is:

= change in freezing point

= freezing point constant =

Thus the freezing point of the solution is .

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.
