1.      What is the normal boiling point of the given liquid?1.      What is the normal boiling point of the given liquid?

• 100K

• 200K

• 300K

• 400K

What the elevation of boiling point when 10g of glucose was added.

• 1K

• 2K

• 3K

• 4K

  If 10g of NaCl is added to the same amount of liquid separately. Which of the following statement will be correct?

• The elevation of boiling point will be same as 10g of glucose

• The elevation of boiling point will be lesser than 10g of glucose

• The elevation of boiling point will be more than 10g of glucose

• Slightly lesser than the addition of 10g of glucose

Calculate the elevation of boiling point if 10.0 g of a non-electrolyte is added to 1Kg of water. Kb of water = 0.52KKgmol-1 and the Molar mass of the solute is 100g/mol. Boiling point of water is 373.15 K

Which of the following can cause max increase in boiling point when added to same amount of solvent?

• 1 mol of glucose

• 2 mol of sucrose

• 1 mol of CaCl₂

• 2 mol of CaCl₂
