Molecular Mass of Gases

а) Сернистый газ (SO2): The molecular mass of sulfur dioxide (SO2) can be calculated by adding the atomic masses of the constituent atoms. Sulfur has an atomic mass of approximately 32.07 u, and oxygen has an atomic mass of approximately 16.00 u. Therefore, the molecular mass of sulfur dioxide (SO2) is approximately 32.07 + 2 * 16.00 = 64.07 u [[1]].

б) Серный ангидрид (SO3): Similarly, the molecular mass of sulfur trioxide (SO3) can be calculated by adding the atomic masses of the constituent atoms. Sulfur has an atomic mass of approximately 32.07 u, and oxygen has an atomic mass of approximately 16.00 u. Therefore, the molecular mass of sulfur trioxide (SO3) is approximately 32.07 + 3 * 16.00 = 80.07 u [[2]].

в) Угарный газ (CO): The molecular mass of carbon monoxide (CO) can be calculated by adding the atomic masses of the constituent atoms. Carbon has an atomic mass of approximately 12.01 u, and oxygen has an atomic mass of approximately 16.00 u. Therefore, the molecular mass of carbon monoxide (CO) is approximately 12.01 + 16.00 = 28.01 u [[3]].

г) Углекислый газ (CO2): The molecular mass of carbon dioxide (CO2) can be calculated by adding the atomic masses of the constituent atoms. Carbon has an atomic mass of approximately 12.01 u, and oxygen has an atomic mass of approximately 16.00 u. Therefore, the molecular mass of carbon dioxide (CO2) is approximately 12.01 + 2 * 16.00 = 44.01 u [[4]].

In summary: - Сернистый газ (SO2): Molecular mass ≈ 64.07 u - Серный ангидрид (SO3): Molecular mass ≈ 80.07 u - Угарный газ (CO): Molecular mass ≈ 28.01 u - Углекислый газ (CO2): Molecular mass ≈ 44.01 u
