This is all I am given:
Assume seawater is a 3.50% solution of NaCl. What is the molality of the solution?
Mass % = [mass component / total mass] x 100
molality = mol solute / kg solvent
Can I use NaCl's molar mass of 58.5g somewhere in the mass percent?
Where am I supposed to get the rest of the numbers from to calculate?
