The percentage composition of carbon by mole in methane (CH4) is:
Some Basic Concepts (Mole Concept) · Class 11 · JEE Main Previous Year Question
The percentage composition of carbon by mole in methane () is:
- a
- b✓
- c
- d
🧠 By mole means count atoms, not weigh them has C and H atoms — atoms total. Mole percent of C is .
🗺️ One quick step
⚠️ The trap is the mass percent of carbon, not the mole percent. Many students see " composition" and jump straight to mass. Read the words "by mole" — they change everything.
