Answer : Option D) Sodium Chloride.
Explanation : Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure surrounding the liquid.
On the basis of bonding, the compound which has highest boiling point is sodium chloride.
Alcohol are found to have boiling point approximately as 78.37 °C.
Glucose usually melts at 146 °C.
Water boils at 100°C.
Sodium chloride has boiling point 1413 °C.
So, it is easy to identify that NaCl (sodium chloride) has highest boiling point amongst the given choices.

Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M
