Explanation:

Step1: Find molar mass of NO₂

Molar mass of NO₂ = 14.01 + 2×16.00 = 46.01 g/mol

Step2: Calculate moles of NO₂

Moles of NO₂ = $\frac{3.50\ \text{g}}{46.01\ \text{g/mol}} ≈ 0.07607\ \text{mol}$

Step3: Relate moles of NO₂ to O₃ (1:1 ratio)

Moles of O₃ = 0.07607 mol

Step4: Find molar mass of O₃

Molar mass of O₃ = 3×16.00 = 48.00 g/mol

Step5: Calculate mass of O₃

Mass of O₃ = 0.07607 mol × 48.00 g/mol ≈ 3.65 g

Answer:

3.65 g
