Questions & Step-by-Step Solutions

If the soil moisture content is 25% and the dry weight of the soil is 200 kg, what is the weight of the water in the soil? (2020)
  • Step 1: Understand that the soil moisture content is given as 25%. This means that 25% of the dry weight of the soil is water.
  • Step 2: Convert the percentage into a decimal for calculation. 25% as a decimal is 0.25.
  • Step 3: Identify the dry weight of the soil, which is given as 200 kg.
  • Step 4: Use the formula to find the weight of the water in the soil: Weight of water = Moisture content × Dry weight.
  • Step 5: Substitute the values into the formula: Weight of water = 0.25 × 200 kg.
  • Step 6: Calculate the result: 0.25 × 200 kg = 50 kg.
  • Step 7: Conclude that the weight of the water in the soil is 50 kg.
  • Soil Moisture Content – The percentage of water present in the soil relative to the dry weight of the soil.
  • Dry Weight of Soil – The weight of the soil when all moisture has been removed.
  • Weight Calculation – Using the formula for calculating the weight of water based on moisture content and dry weight.
