Homework Statement
How many grams of NaCl must you add to 750g of water to make a 0.35 molal solution?
Ans. 7.59g
Homework Equations
[tex]molality=\frac{mol_{solute}}{kg_{solvent}}[/tex]
MW of NaCl = 23 + 35.45 = 58.45 g/mole
The Attempt at a Solution
[tex]0.35mol/kg=\frac{mass(\frac{1mole}{58.45g})}{0.750kg}[/tex]
[tex]mass = 15.33g[/tex]
