Question

A solution is made by mixing 250g hexane and 50g octanol, mass percent of octanol is

A) 20%

B) 16.66%

C) 83.3%

D) 50%​

Answer 1

Given:-

☆Mass of octanol(solute)=50g

☆Mass of hexane(solvent)=250g

To find:-

☆Mass percent of octanol(concentration of solution)

Solution:-

Mass of the solution=Mass of solute+Mass of solvent

=>(250+50)g

=>300g

Now,Concentration of solution:-

=>Mass of solute/Mass of solution×100

=>50/300×100

=>100/6

=>16.66%

Hence,mass percent of octanol is 16.66% and correct option is (B)
