  1. 50% (50 Percent)

  2. 40% (40 Percent)

  3. 20% (20 Percent)

C Correct answer
Explanation

Concentration is calculated as (mass of solute / mass of solution) * 100. Here, (110 / 550) * 100 = (1/5) * 100 = 20%.

AI explanation

The concentration of a solution is calculated by dividing the mass of the solute by the total mass of the solution and multiplying by 100. Here, the concentration equals 110 divided by 550 and then multiplied by 100. This simplifies to 20 percent.
