If fine aggregate has a dry weight of 300g and a wet weight of 302g, what is the moisture content percentage?

To determine the moisture content percentage of the fine aggregate, you first need to calculate the moisture content in grams, which is the difference between the wet weight and the dry weight. In this case, the wet weight is 302g and the dry weight is 300g.

The moisture content can be calculated as follows:

Moisture Content (g) = Wet Weight - Dry Weight

Moisture Content (g) = 302g - 300g = 2g

Next, to find the moisture content percentage, you use the formula:

Moisture Content Percentage = (Moisture Content (g) / Dry Weight (g)) × 100

Moisture Content Percentage = (2g / 300g) × 100 = 0.66667%

When rounding to two decimal places, this value is approximately 0.67%. Thus, the moisture content percentage of the fine aggregate is 0.67%. This is why the correct answer is represented as the first choice. It reflects an accurate application of the moisture content formula and the conversion to percentage, essential for understanding aggregate properties in construction and material sciences.
