Answer:
<u>The molal boiling point elevation constant is 1.59 ≈ 1.6</u>
Explanation:
To solve this question , we will make use of the equation ,
Δ
<em>where , </em>
- <em>Δ
is the change in boiling point of the substance
( °
or
)</em>
- <em>
is the Vant Hoff Factor which = 1 in this case ( no unit )</em>
- <em>
is the mola boiling point elevation constant of X (
)</em>
- <em>
is the molality of the solution which has
as the solute and
)</em>
- Δ
°
∴
- <em>as the weight of
and thus number of moles =
</em>
- <em>and the weight of solvent in
is
</em>
