11 g S

Step 2: Identify Conversions

[PT] Molar Mass of S - 32.07 g/mol

Step 3: Convert

Set up: $\displaystyle 11 \ g \ S(\frac{1 \ mol \ S}{32.07 \ g \ S})$
Multiply/Divide: $\displaystyle 0.343 \ mol \ S$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

0.343 mol S ≈ 0.34 mol S
