The density of 3M3 \mathrm{M}3M solution of NaCl\mathrm{NaCl}NaCl is 1.0 g mL−11.0 \mathrm{~g} \mathrm{~mL}^{-1}1.0 g mL−1. Molality of the solution is ‾×10−2 m\underline{\hspace{2cm}}\times 10^{-2} \mathrm{~m}​×10−2 m. (Nearest integer). Given: Molar mass of Na\mathrm{Na}Na and Cl\mathrm{Cl}Cl is 232323 and 35.5 g mol−135.5 \mathrm{~g} \mathrm{~mol}^{-1}35.5 g mol−1 respectively.
