Question

calculate the molality of nitric acid solution in which mole fraction of nitric acid is 0.2​

Answer 1

Answer:

13.877

Explanation:

let o.2 be the moles of nitric acid then moles of solvent=0.8 moles

mass of solvent= 0.8*18.015/1000=0.014412 kg

molality of nitric acid= moles /litre

0.20/0.014412= 13.877 m
