Question

Determine the mass by mass percentage concentration of a 100g salt solution which
contains 20g salt? (AS)
Ans: (20%)
interms of mass by volume percentage of the solution
oride (KCl)solution?​

Answer 1

$\sf {\red {Answer \: :}}$

Mass of solute = 20 g

Mass of solution = 100 g

Mass % = Mass of solute /Mass of Solution × 100

Mass % = 20/100 × 100

Mass % = 20 %
