How much would the boiling point of water increase if 4 mol of sugar were added to 1 kg of water (kb = 0.51°c/(mol/kg) for water and i = 1 for sugar)?

2.04°C

Explanation:

Answer : The boiling point of water increases,

Solution : Given,

Moles of solute (sugar) = 4 moles

Mass of solvent (water) = 1 Kg

i = 1 for sugar

Formula used :

Where,

= elevation in boiling point

= elevation constant

m = molality

= moles of solute (sugar)

= mass of solvent (water)

i = van't Hoff factor

Now put all the given values in this formula, we get the elevation in boiling point of water.

Therefore, the elevation in boiling point of water is

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
