Using Dimensional AnalysisExplanation:

Step 1: Define

0.75 mol SO₂

Step 2: Identify Conversions

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

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of SO₂ - 32.07 + 2(16.00) = 64.07 g/mol

Step 3: Convert

Set up:                              Multiply/Divide:                

Step 4: Check

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

48.0525 g SO₂ ≈ 48 g SO₂

B"hf and f-"  is the correct answer took the test on edgenuity and got it right
