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

Step 3: Convert

  1. Set up:                                [tex]\displaystyle 11 \ g \ S(\frac{1 \ mol \ S}{32.07 \ g \ S})[/tex]
  2. Multiply/Divide:                  [tex]\displaystyle 0.343 \ mol \ S[/tex]

Step 4: Check

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

0.343 mol S ≈ 0.34 mol S
