<u>Answer:</u> The molality of barium chloride solution is 0.289 m
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = 748 mL
Putting values in above equation, we get:
To calculate the molality of solution, we use the equation:
where,
= Given mass of solute (barium chloride) = 45.0 g
= Molar mass of solute (barium chloride) = 208.23 g/mol
= Mass of solvent (water) = 748 g
Putting values in above equation, we get:
Hence, the molality of barium chloride solution is 0.289 m
