wt of solute \(=30\,gm\)
Volume of solution \(=100\,mL\)
wt. of solution \(=1.2 \times 100=120\,gm\)
wt. of solvent \(=120-30=90\,gm\)
\(m =\frac{30 \times 1000}{180 \times 90}=1.85\)
\(\frac{24- P _{ s }}{ P _{ s }}=\frac{1.85 \times 18}{1000}\)
\(24- P _{ s }=0.0333 P _{ s }\)
\(P _{ s }(1.033)=24\)
\(P _{ s }=23.22\)
