The molar mass of elemental oxygen and oxygen gas are differentGroup of answer choicesTrueFalse

Step 1: Define the Problem

Determine whether the molar mass of elemental oxygen and oxygen gas are different.

Step 2: Break Down the Problem

• Identify the molar mass of elemental oxygen.
• Identify the molar mass of oxygen gas.

Step 3: Apply Relevant Concepts

• Elemental oxygen refers to a single oxygen atom (O).
• Oxygen gas refers to the diatomic molecule (O₂).

Step 4: Analysis, Verify and Summarize

• The molar mass of a single oxygen atom (O) is approximately 16 g/mol.
• The molar mass of oxygen gas (O₂) is approximately 32 g/mol (since it consists of two oxygen atoms).

Final Answer

True. The molar mass of elemental oxygen and oxygen gas are different.
