Asolution is made by dissolving 3.8 moles of sodium chloride (nacl) in 185 grams of water. if the molal boiling point constant for water (kb) is 0.51 °c/m, what would be the boiling point of this solution? show all of the work needed to solve this problem.

The molality of the solution can be defined as moles of solute per kilogram of solvent.

Molality=3.8 moles/0.185 kg

=20.54 molal

The change in the temperature can be calculated as the product of boiling point constant and molality.

ΔTb=Kb×m=0.51 °C/m×20.54 m=10.47 °C.

The boiling point of the solution will be = 100 °C + 10.47 °C

=110.47 °C

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

i think its 5049.

i hope this !
