Answer: 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

K is potassium and Cl2 is Chlroine.
K has a charge of +1 and Cl2 has a charge of -1
KCl2 is Potassium Chloride
When the two elements are introduced and heated, they will react violently and cause a fire.
