Question

a solution content 60 g of common salt in 340 g of water calculate the concentration in terms of mass by mass percentage of the solution​

Answer 1

Explanation:

mass of solute (NaCl) = 60g

mass of solvent (water) =340g

mass of solution= 60 + 340 => 400g

concentration of solution=

(mass of solute ÷ mass of solution)×100

(60÷400)×100

60÷4

15%
