No. m = mols solute/kg solvent. molsl Na2SO4 is not 11.1. The problem lists that as grams. and 2269.2 is not kg. I didn't write 100 anywhere in my instructions. You're not thinking straight.
so 1 divided by 2.2692
Yes, that is kg solvent. Now convert 11.1 g Na2SO4 to mols. mols = grams/molar mass = ?
is that .44068?
No. What's the molar mass of Na2SO4?
oh 142.04
ok. Now what is 11.1 grams Na2SO4 converted to mols?
