Question 1 Report

In an experiment determine the percentage of organic matter in a soil sample, the following data was collected; weight of over-dried soil before burning = 50g
weight of over-dried soil after burning = 28g. Use the information to answer this question.

Determine the percentage of organic matter in the soil 

Answer Details
To determine the percentage of organic matter in the soil, we need to calculate the weight of the organic matter that was lost during the burning process. The weight of the organic matter can be calculated as follows: Weight of over-dried soil before burning - Weight of over-dried soil after burning = Weight of organic matter Substituting the given values, we get: 50g - 28g = 22g Therefore, the weight of organic matter is 22g. To calculate the percentage of organic matter, we need to divide the weight of organic matter by the weight of over-dried soil before burning and multiply by 100. (22g / 50g) x 100 = 44% Therefore, the percentage of organic matter in the soil is 44%. So the correct option is "44%".
