Answer 1

Hey mate here is ur answer

❤❤

Explanation:

$solute = common \: salt = 20g \\ solvent = water = 320g \\ therefore \\ mass \: of \: solution = (320 + 20)g \\ = 340g \\ mass \: by \: mass \: concentration \\ = \frac{mass \: of \: solute}{mass \: of \: solution} \times 100\% \\ = \frac{20}{340} \times 100\% \\ = \frac{2000}{340} \%\\ = 5.88\% \: ans.$

Hope this helps
