МатематикаВопрос:
Fill the table based on the provided information. Calculate the molar masses of the gases and fill in the table.
Ответ:
Таблица с рассчитанными молярными массами:
| № п/п | Название вещества | Формула | Молярная масса, г/моль |
|---|---|---|---|
| 1 | Аргон | Ar | 39.95 |
| 2 | Кислород | O₂ | 32.00 |
| 3 | Аммиак | NH₃ | 17.03 |
Обоснование:
- Аргон (Ar): Молярная масса = 39.95 г/моль (по периодической таблице).
- Кислород (O₂): Молярная масса = 2 * 16.00 = 32.00 г/моль (атомная масса кислорода ≈ 16.00 г/моль).
- Аммиак (NH₃): Молярная масса = 14.01 + 3 * 1.01 = 17.04 г/моль (атомная масса азота ≈ 14.01 г/моль, водорода ≈ 1.01 г/моль).
