Question

1.74 kmol sulfur trioxide
m_{so_3} =
g

Explanation:

Step1: Find molar mass of SO₃

Molar mass of S = 32.07 g/mol, O = 16.00 g/mol.
Molar mass of SO₃ = 32.07 + 3×16.00 = 80.07 g/mol.

Step2: Convert kmol to mol

1.74 kmol = 1.74 × 10³ mol.

Step3: Calculate mass of SO₃

Mass = moles × molar mass = 1.74×10³ mol × 80.07 g/mol = 139321.8 g.

Answer:

139321.8
