Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other has carbon tetrachloride as the solvent. determine the molal concentration, (or and boiling point, . solvent normal boiling point (∘ (∘/ benzene 80.1 2.53 carbon tetrachloride 76.8 5.03

Hey there!:

Δt =  m * Kf

Boiling point of a solution =>  Boiling point + Δt ( Kc * m )

Boiling point of benzene solution => 80.1 + 2.53 m

Boiling point of CCl₄ solution => 76.8 +5.03 m

Since the boiling points are the same 80.1 + 2.53 m = 76.8 +5.03 m

3.3 = 2.5 m

m =  3.3 / 2.5 => 1.32 moles of solute per kg of solvent

Bp =   80.1 + 2.53 * 1.32 => 83.4396 ºC

Hope this helps!

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
