Suppose you had 10 mol of nacl and you dissolved it in exactly 3.00 kg of pure water (the solvent). what would be the molality of the solution in mol/kg?

the answer would be c

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
