To find the total mass of compound [tex]$A$[/tex], follow these steps:
1. Identify the given masses of the elements in Sample A:
- Mass of sulfur (S) in Sample A: 32.0 grams
- Mass of oxygen (O) in Sample A: 48.0 grams
2. Calculate the total mass of compound A:
[tex]\[
\text{Total mass of compound A} = \text{Mass of sulfur} + \text{Mass of oxygen}
\][/tex]
Plugging in the provided values:
[tex]\[
\text{Total mass of compound A} = 32.0 \, \text{g} + 48.0 \, \text{g}
\][/tex]
3. Compute the sum:
[tex]\[
\text{Total mass of compound A} = 80.0 \, \text{g}
\][/tex]
Thus, the total mass of compound [tex]$A$[/tex] is:
[tex]\[
\boxed{80.0 \, \text{g}}
\][/tex]
