Answer:
0.13 m of → Highest boiling point
0.19 m of → Second Highest boiling point
0.17 m of → Third highest boiling point
0.31 m Sucrose (nonelectrolyte) → Lowest boiling point
Explanation:
Elevation in boiling is given by :
Where :
i = van't Hoff factor
= Molal Elevation constant of solvent
m = molaity of the solution
1) 0.19 m of
i = 2 (electrolyte)
Molality of the solution = 0.19
Elevation is boiling point of solution:
2) 0.17 m of
i = 2 (electrolyte)
Molality of the solution = 0.17
Elevation is boiling point solution :
3) 0.13 m of
i = 3 (electrolyte)
Molality of the solution = 0.13
Elevation is boiling point solution :
4) 0.31 m Sucrose (nonelectrolyte)
i = 1 ( non electrolyte)
Molality of the solution = 0.31 m
Elevation is boiling point solution :
Higher the value of elevation in temperature higher will be the boiling point of the solution .
The decreasing order of solution from highest boiling point to lowest boiling point is :
0.13 m of → Highest boiling point
0.19 m of → Second Highest boiling point
0.17 m of → Third highest boiling point
0.31 m Sucrose (nonelectrolyte) → Lowest boiling point
The empirical formula : MnO₂.
<h3>Further explanation</h3>Given
632mg of manganese(Mn) = 0.632 g
368mg of oxygen(O) = 0.368 g
M Mn = 55
M O = 16
Required
The empirical formula
Solution
You didn't include the pictures, but the steps for finding the empirical formula are generally the same
- Find mol(mass : atomic mass)
Mn : 0.632 : 55 = 0.0115
O : 0.368 : 16 =0.023
- Divide by the smallest mol(Mn=0.0115)
Mn : O =
The empirical formula : MnO₂
