To find the mass percent of sulfur in compound A, follow these steps:
1. Identify the total mass of the compound: For compound A, the total mass is 80.0 grams.
2. Identify the mass of sulfur in the compound: For compound A, the mass of sulfur is 32.0 grams.
3. Calculate the mass percent of sulfur: The mass percent of sulfur is given by the formula: [tex]\[
\text{Mass percent of sulfur} = \left( \frac{\text{Mass of sulfur}}{\text{Total mass of the compound}} \right) \times 100
\][/tex]
4. Plug in the values: Substituting the given values into the formula, we get: [tex]\[
\text{Mass percent of sulfur} = \left( \frac{32.0 \text{ g}}{80.0 \text{ g}} \right) \times 100
\][/tex]
5. Simplify the fraction: The fraction [tex]\(\frac{32.0}{80.0}\)[/tex] simplifies to [tex]\(\frac{2}{5}\)[/tex].
6. Calculate the percentage: Converting the simplified fraction to a percentage: [tex]\[
\left( \frac{2}{5} \right) \times 100 = 0.4 \times 100 = 40.0
\][/tex]
Thus, the mass percent of sulfur in compound A is [tex]\(40.0\%\)[/tex].
