Change in boiling point = (i)(m)(K)i = van't Hoff factor which for NaCl is 2 (2 particles form upon ionization)
m = molality = moles/kg = 4 moles/1 kg = 4
K = boiling point constant for water = 0.512 degrees/m
∆T = (2)(4)(0.512) = 4.1 degrees
So, the boiling point of water would increase by 4.1 degrees C (4 degrees to 1 sig. fig.)

What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
Does soy sauce affect the boiling point of water?
Any material added to water raise the boiling point.
What would the final boiling point of water be if 3 mol of NaCl were added to 1 kg of water (Kb 0.51 and degC(molkg) for water and i 2 for NaCl)?
103.06 degrees C
Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
How does pure water increase the boiling point?
Pure water does not increase - or in any other way affect - the boiling teperature of water becasue the latter is normally taken to be that for pure water!The question does not make sense. What type of water is it whose boiling temperature is meant to be increased by pure water? Impure water?In any case, pure water does not increase the boiling point of water but lowers it.
Wha happen to boiling point when gelatin is added to water?
The boiling point of water will increase if gelatin will be added to the water. The reason for this is because gelatin adds to the concentration of the liquid resulting to higher boiling point.
How much would the boiling point of water increase if 4 mole of sugar were added to 1 kg of water?
The increase of the boiling point is only 2 0C.
How much would the boiling point of water increase if 4 mol of sugar were added to 1 kg of water?
The boiling point of water become 102 oC.
What are the effects of impurities in boiling and freezing point?
AnswerImpurities tend to increase the boiling point and lower the freezing point.in a way boiling point of salty water > boiling point of fresh waterfreezing properties of salty water < freezing properties of fresh watermelting properties of salty water < melting properties of fresh water.Salt water, contains NaCl, which ionizes into Na and Cl ions. when ions are added to a solvent, such as water, they tend to increase the boiling point and lower the melting point.
What is the effect of NaCl and CaCl2 on the boiling point of water?
The water with solved ions has greater boiling point. The dissolved salts increase the boiling point of water.

What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
Is there a difference in boiling point in water and sulphur water?
Any added impurity can change the boiling point of a liquid.
Does soy sauce affect the boiling point of water?
Any material added to water raise the boiling point.
What would the final boiling point of water be if 3 mol of NaCl were added to 1 kg of water (Kb 0.51 and degC(molkg) for water and i 2 for NaCl)?
103.06 degrees C
Does sugar affect the boiling point of water?
Adding sugar to boiling water it will increase the boiling temperature very slightly
