1357just find the concentration of the solution.
based on that you can know the amount of solvent present in the solution.
subtract that amount from total amount given.
10=1.86*m
m=10/1.86=moles of solute/(wt. of solvent)
wt. of solvent=moles of solute*1.86/10=(25*1.86/620)=75 gm
ice separated out=100-75=25 gms
