◆ Answer- 26.47 %

◆ Explanation-

# Given-

• m = 72 g

• M = 200 g

• T = 20 °C

# Solution-

➼Concentration of the solution is given by-

➼C = mass(solute) / mass(solution) × 100

➼C = m / (m+M) × 100

➼C = 72 / (72+200) × 100

➼C = 72 / 272 × 100

∴C = 26.47 %

Concentration of the solution is 26.47 % .

Answer 2

Answer:

26.4%

Explanation:

Mass of Solute=72g

Mass of Solvent=200g

Mass of Solution=72g+200g

                            =272g

Concentration=(72/272)*100

                        =7200/272

                        =26.470%
