Question

the vapour
pressure of 2% of
an
aquous solution of non-electrolyte at 100%. c
is 755 nm.
Calculate molar mass
of solute .​

Answer 1

Answer:

So mass of non-electrolyte =2.1 g(W2). Molar mass of water (M1)=18 g. Molar mass of non-electrolyte(M2)=? vapour pressure of the solution = 755 mm HG

I hope it helps u ✌️
