To calculate the mass of 3.65 x 10^20 molecules of SO3, first calculate the molar mass of SO3 (80.06 g/mol). Next, convert the number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). Finally, use the molar mass to convert moles to grams.

Mass of 3.65 x 10^20 molecules of SO3 = (3.65 x 10^20 molecules / 6.022 x 10^23 molecules/mol) * 80.06 g/mol ≈ 0.49 g.

How do you form oleum from sulfuric acid?

Oleum is formed by dissolving sulfur trioxide gas in concentrated sulfuric acid. Sulfur trioxide can be introduced into concentrated sulfuric acid slowly and under controlled conditions to prevent excessive heat generation and to ensure proper mixing. This process results in the formation of oleum, which is a solution of sulfuric acid containing excess sulfur trioxide.
