Asked by an

a solution is made by dissolving 25 g NaCl in enough water to make 1.0 L solution. Assume that density of the solution is 1.0 g/mL. calculate the mass percent, molarity, molality, and mole fraction of NaCl.

help please

25g/58.44g NaCl=.428 mol

1000 grams of solvent H20

25g/58,44 g x100= 42.8 % mass percent

molarity .428 mol/1.0 L= .428 M

molality= .428 mol/1 Kg= .428 molal is that right?

help please
