I'm pretty sure the density terms are in g/cc

How about you put both of these things and see if the formulas work, back calculate it no? Try and put kg and gram and figure it out. But here's a huge word of caution. All these formulas are pointless and I'm being very, very straight with you. Okay? Why I'm saying pointless is because you can't possibly mung 100 formulas of physical chemistry. We just need to know basics. Density is what? Total mass by total volume. Now density could be kilogram per litre or it could be gram per cc. Usually it's given as gram per cc. Molarity is moles of solute by litre of solution. It's important to add of solute and of solution. Okay? This is also important. Molality is moles of solute in 1 kg of solvent. Need to write solute and solvent. That is it. Those are the things you need to mung. Rest everything else you can derive on the spot. And derive it 10 times, you'll remember it.

My teacher gave us four simple formulae to remember. With derivation though, in case we can't memorise

Ok I tried it and grams is the right one I'll deriving them now

yes sir, even with the generalised case we can always manipulate it according to question specific scenario, i mean mugging all would actually be dangerous if someone gets confused in the exam or smthng. the most important thing imo would be the proper definations of these terms, along with their most basic mathmetical forms 🙏 .

Well done.

yup seems like as they all have a "1000" term added to fix that back to SI units.....
