Question

how many atoms are there in exactly 12g of carbon -12element ?​

Answer 1

Answer:

mark me brainlist

Explanation:

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).

Answer 2

Answer:

The value of the mole is equal to the number of atoms in exactly 12 gram of pure carbon 12. 12.00 gram C-12 atoms=6.022*1023 atoms. The number of particles in 1 mole is called Avogadro's Number (6.0221421*1023).
