Hello buddy
Here is your answer

molality= no. of moles of solute/mass of solvent
saurabh aap bhi send kar do solve
ok
Hmmm
%w/w = 20 20=20×100/100. mass of solute = 20. mass of solution =100. mass of solvent= 100-20= 80. no. of moles of solute= 20/138. mass of solvent in kg=0.080 molality= 1.811 m
%w/w=mass of solute×100/mass of solution. = 20=20×100/100. (if u have doubt)
thanks bro.
pleasure

thank u
