Answer 2

The weight of 1 gram molecule of Ag (silver) is equal to 108g

• The term "one gram molecule" is often used in place of 1 mole, that is, 1 gram molecule of substance is equivalent to 1 mole of that substance.
• One mole of Ag has 6.023 × 10²³ atoms and it weighs 108 grams and not 6.023 × 10⁻² grams.

Hence, in the given question, (Option 2) One gram molecule of silver equals 6.023 × 10⁻² g is incorrect, the answer is (Option 2).
