Questions & Step-by-Step Solutions

If 10 liters of a solution contains 30% salt, how much salt is present in the solution?
  • Step 1: Understand that 30% means 30 out of every 100 parts.
  • Step 2: We have 10 liters of solution.
  • Step 3: To find out how much salt is in the solution, we need to calculate 30% of 10 liters.
  • Step 4: Convert 30% to a decimal by dividing by 100: 30% = 30 / 100 = 0.3.
  • Step 5: Multiply the decimal (0.3) by the total volume of the solution (10 liters): 0.3 * 10 = 3 liters.
  • Step 6: Therefore, there are 3 liters of salt in the solution.
  • Percentage Calculation – Understanding how to calculate a percentage of a total quantity.
  • Volume Measurement – Recognizing that liters are a unit of volume and applying it to the context of solutions.
