What is the percent volatile solids if the ash weight is 0.0103g and the dry weight is 0.0149g?

To find the percent of volatile solids in a sample, the formula used is:

[

\text{Percent Volatile Solids} = \left( \frac{\text{Dry Weight} - \text{Ash Weight}}{\text{Dry Weight}} \right) \times 100

]

In this scenario, the dry weight of the sample is given as 0.0149g and the ash weight is given as 0.0103g.

First, calculate the weight of the volatile solids:

[

\text{Volatile Solids} = \text{Dry Weight} - \text{Ash Weight} = 0.0149g - 0.0103g = 0.0046g

]

Next, plug this value into the formula:

[

\text{Percent Volatile Solids} = \left( \frac{0.0046g}{0.0149g} \right) \times 100

]

Calculating this gives:

[

\text{Percent Volatile Solids} = \left(0.3087\right) \times 100 \approx 30.87%

]

This value indicates the percentage of
