Question

Calculate the number of different atoms in 0.2 mol ethene​

Answer 1

1.204 × 10²³

Step-by-step explanation:

The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.

To convert moles to atoms, multiply the molar amount by Avogadro's number.

(6.022 × 10²³) × 0.2

= 1.204 × 10²³
