Question

• Boiling point of water at 750 mm Hg is 96.63°c
How much surose is to be added to 500g of
water such that it boils at 100°c ? Molal
elevation constant for water is 0.52kgmol
a) 11.08kg 6) 1108.2g
6) 1108.2kg d) 11.08g​

Answer 1

Answer:

refer

find

elevation of in b.p =b.p of solution -b.p of solvent

second formula

elevation of b.p=kb*molalilty

kb=0.52

m=moles of solute/mass of solvent

you have to find mass of solute

hope so helpful
