Mole Concept And Molar Masses

We are given:

• Number of moles of gas
• Nature of gas: Triatomic Each molecule contains 3 atoms
• Avogadro's number molecules per mole

Step-by-step calculation: Since each molecule has 3 atoms (because it’s triatomic), the total number of atoms will be: This value is not among the given options, but we must recheck carefully. Wait! The correct multiplication is: Each molecule has 3 atoms: So, the correct option is:
