Question

10 gram of salt is dissolved in 25 gram of water. Calculate the percentage amount of the salt in

the solution.​

Answer 1

Answer:

28.57%

Explanation:

Weight of salt = 10g

Weight of water = 25g

=> Weight of solution = 10 + 25 = 35g

=> $Salt \% = (\frac{10}{35} )(100)$

=> $Salt\% = \frac{1000}{35}=28.57\%$

Answer 2

Answer:

Explanation: according to the theory of conservation of mass proposed by Lavosier,

total mass of solution = mass of solute + mass of solvent

                                      = 10+25

                                      = 35gm

%(w/w) = total mass of solute / total mass of solution

             = 10/35 *100

            approx= .29 *100

            approx= 29%(w/w)
