A) 6% urea solution by weight of solution
B) 18% glucose solution by weight of solution
C) 34.2% sucrose solution by weight of solution
D) All have equal boiling points
Correct Answer: C
Solution :
[c] \[\Delta {{T}_{b}}=\frac{1000{{K}_{b}}{{w}_{1}}}{{{m}_{1}}{{w}_{2}}}\] Boiling point of solution \[=(373+\Delta {{T}_{b}})\] The larger the value of \[\Delta {{T}_{b}}\], the higher the boiling point.\[{{w}_{1}}\] | \[{{w}_{2}}\] | \[{{m}_{1}}\] | \[\Delta {{T}_{b}}\] | Boiling point | |
