Answer 1

Your answer is A

6.02 × 1023 particles

Answer 2

Answer:
`6.022* 10^(23)`

Step-by-step explanation: According to Avogadros law, one mole of any substance contains a fixed number of particles i.e
`6.022* 10^(23)` particles (atoms, molecules or ions) which is also known by the name Avogadro's number.

For example: 1 mole of
`O_2` molecule contains
`6.022* 10^(23)` molecules of oxygen.

1 mole of
`He` contains
`6.022* 10^(23)` atoms of helium.
