From the information above, determine the percentage of water in the given soil sample?
Answer Details
To determine the percentage of water in the soil sample, we need to first calculate the mass of dry soil in the sample. This can be done by subtracting the mass of the empty crucible from the mass of the crucible and soil after heating:
Mass of dry soil = Mass of crucible and soil before heating - Mass of crucible and soil after heating
Mass of dry soil = 29g - 18g
Mass of dry soil = 11g
Next, we can calculate the mass of water in the soil sample by subtracting the mass of dry soil from the initial mass of the sample:
Mass of water = Mass of crucible and soil before heating - Mass of dry soil
Mass of water = 29g - 11g
Mass of water = 18g
Finally, we can calculate the percentage of water in the sample by dividing the mass of water by the initial mass of the sample and multiplying by 100:
Percentage of water = (Mass of water / Mass of crucible and soil before heating) x 100%
Percentage of water = (18g / 29g) x 100%
Percentage of water = 62.07%
Therefore, the percentage of water in the given soil sample is approximately 62.07%. None of the answer options provided match this value exactly, so the closest option would be 50%.
