Question: If the soil moisture content is 25% and the weight of the dry soil is 200 kg, what is the weight of the water in the soil? (2022)

Options:

Correct Answer: 50 kg

Exam Year: 2022

Solution:

Weight of water = Moisture content x Weight of dry soil = 0.25 x 200 kg = 50 kg.

If the soil moisture content is 25% and the weight of the dry soil is 200 kg, what is the weight of the water in the soil? (2022)

If the soil moisture content is 25% and the weight of the dry soil is 200 kg, what is the weight of the water in the soil? (2022)

Step 1: Understand that the soil moisture content is given as a percentage, which means it represents the amount of water in the soil compared to the weight of the dry soil.
Step 2: Convert the moisture content percentage into a decimal. Since the moisture content is 25%, we convert it to decimal form by dividing by 100: 25% = 25/100 = 0.25.
Step 3: Identify the weight of the dry soil, which is given as 200 kg.
Step 4: To find the weight of the water in the soil, multiply the moisture content (in decimal form) by the weight of the dry soil: Weight of water = 0.25 x 200 kg.
Step 5: Calculate the result: 0.25 x 200 kg = 50 kg.
Step 6: 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 weight of the dry soil.
Weight Calculation – Using the formula to calculate the weight of water based on moisture content and dry soil weight.
