Question

calculate the mass of NaCl in 5 molal solution? (plzz give me full solution not only answer) ​

Answer 1

I'm not sure about this answer because mass of solvent isn't given here...

Molality = Moles of solute ÷ Mass of solvent

If mass of solvent is 1Kg then,

Moles of solute = 1kg × 5

Moles of solute = 5

Here solute is NaCl

Therefore,

One mole of NaCl has 58.5 grams of it...

Then, 5 moles will have = 58.5 × 5 = 292.5 grams
