The common laboratory solvent diethyl ether (ether) is often used to purify substances dissolved in it. the vapor pressure of diethyl ether, ch3ch2och2ch3, is 463.57 mm hg at 25°c.
1. in a laboratory experiment, students synthesized a new compound and found that when 21.47 grams of the compound were dissolved in 233.8 grams of diethyl ether, the vapor pressure of the solution was 455.55 mm hg. the compound was also found to be nonvolatile and a non-electrolyte. what is the molecular weight of this compound?

386.0 g/mol

Explanation:

As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.

The formula for relative lowering of vapor pressure will be,

where,

= relative lowering in vapor pressure

i = Van'T Hoff factor = 1 (for non electrolytes)

= mole fraction of solute  =

Given : 21.47 g of compound X is present in 233.8 g of diethyl ether

moles of solute (X) =

moles of solvent (diethyl ether) =

= mole fraction of solute =

The molecular weight of this compound is 386.0 g/mol

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
