Answer:

105 g O₂

Step-by-step explanation:

Step 1: Define

Molar Mass O - 16.00 g/mol

Molar Mass O₂ - 2(16.00) = 32.00 g/mol

Step 2: Use Dimensional Analysis

$3.28 \hspace{3} mol \hspace{3} O_2(\frac{32 \hspace{3} g \hspace{3} O_2}{1 \hspace{3} mol \hspace{3} O_2} )$ = 104.96 g O₂

Step 3: Simplify

We are given 3 sig figs.

104.96 g O₂ ≈ 105 g O₂
