The formula to calculate Percent by Weight (% by wt.) is:
\[ \% \text{ by wt.} = \frac{\text{gSolute}}{100 \text{gSolution}} \]
Where:
Percent by Weight is the total volume of solution.
Gram of Solute is the total grams of solute present in the solution.
100 g of Solution represents the solution whose weight is 100 grams.
Let's assume the following values:
Using the formula:
\[ \% \text{ by wt.} = \frac{\text{gSolute}}{100 \text{gSolution}} \]
Evaluating:
\[ \% \text{ by wt.} = \frac{0.02}{0.1} \]
The Percent by Weight is 0.2.
