Avogadro's number is equal to__________________?
Correct answer: B. 6.023 x 10^23 molecules/gm.mole
- A. 6.023 x 10^23 molecules/kg.mole
- B. 6.023 x 10^23 molecules/gm.mole
- C. 6.023 x 10^16 molecules/kg.mole
- D. 6.023 x 10^26 molecules/gm.mole
Explanation
One gram-mole contains approximately 6.023 × 10²³ molecules, which is Avogadro’s number. A kilogram-mole contains 1000 times as many molecules, so option A has the wrong unit conversion.
