What is the change in the boiling point of a solution made by dissolving 14.7 g of c6h12o6 into of water? the density of water is and ?

First determine the molality of the solution. m = (w solute)/[(mm solute)(kg solvent)] -- mm means molar mass. So,

m = (14.7 g)/[(180 g/mol)(0.150 kg) =0.544 mol/kg = 0.544 m

Change in boiling point (∆t) = m x Kbp = (0.544 m)(0.512 °C/m) = 0.28°C

The solution will boil at 100.28°C at 1 atm.

the density if water is 1.00 g/ml and Kb= 0.512 C/m

you need to give more information

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.
