Question

what is the strength(percent concentration of salt) of 30 kg of a salt solution made by dissolving 1.2 kg of salt in water

Answer 1

(1.2 kg / 30 kg) x 100 = 4% solution

Answer 2

30kg of salt solution.

 

Water content=30-1.2=28.8 kg

 

This water contains 1.2 kg of salt

 

Salt Concentration in % = (1.2/28.8)*100

 

                                   =4.16%
