Question

Which one of the following i.e., number of molecules per gram molecular weight, represents the Avogadro’s number (N)?

• A. 6.02 × 10¹
• B. 6.02 × 10²
• C. 6.02 × 10²³
• D. 6.02 × 10³¹

Hint:

Avogadro’s number is always 6.022 × 1023—associate it with ”molecules per mole.”

Answer 1

The Correct Option is C

Avogadro’s number, NA, is defined as the number of molecules (or atoms) in one mole of a substance. It has a fixed value of \(6.022 × 10^{23}\) molecules/mol.
