Question

One mole is the amount of a substance that contain as many particles or entities as there are atoms in

Answer 1

Answer:

12 g C-12

Explanation:

One is the amount of a substance that contains as many particles as there are atoms in 12 g C-12 i.e. an isotope of Carbon

Answer 2

One mole contains as many particles as in 12 grams of pure carbon-12

• One mole of a given compound/element etc is the amount of the substance that contains 6.023 × 10²³ particles/constituents in it.

• In about 12 grams of pure Carbon - 12 element, the amount of carbon particles/atoms present is equivalent to 6.023 × 10²³ particles/atoms.
• Thus, it can be said that one mole of a given substance contains as many particles as is present or found in about in 12 grams of pure carbon-12
