The formula to calculate the percent of a substance in grams (G) is:
\[ G = \frac{TM \times POM}{100} \]
Where:
A percent to grams calculation determines the total number of grams of a substance in a mixture based on its percentage of the total mass.
Let's assume the following values:
Using the formula to calculate the total number of grams of substance (G):
\[ G = \frac{200 \times 25}{100} = 50 \]
The total number of grams of substance (G) is 50 grams.
