Questions & Step-by-Step Solutions

A solution contains 10% salt. If 200 ml of the solution is taken, how much salt is in it?
  • Step 1: Understand that 10% means 10 out of every 100 parts is salt.
  • Step 2: We have a total of 200 ml of solution.
  • Step 3: To find out how much salt is in 200 ml, we calculate 10% of 200 ml.
  • Step 4: Convert 10% to a decimal. 10% = 10/100 = 0.1.
  • Step 5: Multiply the decimal by the total volume: 0.1 * 200 ml.
  • Step 6: Calculate the result: 0.1 * 200 = 20 ml of salt.
  • Percentage Calculation – Understanding how to calculate a percentage of a given quantity.
  • Volume to Mass Conversion – Recognizing that the density of the solution is not provided, but assuming it is similar to water for simplicity.
