Question

vapour pressure of water at 293k is 17.51mm lowering vapour pressure of sugar solutions is 0.0614mm calculate relative lowering of vapour pressure .​

Answer 1

Okay!

so basically P* ie vapour pressure of water is given also we have Ps vapour pressure of solution !

The formula for relative lowering is (P*-Ps/P*)!!

Hence by putting values we get the answer as (17.51-0.0614/17.5)

which is equal to 0.997atm!!

That's your answer!!
