Answer 1

Your answer is A

6.02 × 1023 particles

Answer 2

Answer: $6.022\times 10^{23}$

Explanation: According to Avogadros law, one mole of any substance contains a fixed number of particles i.e $6.022\times 10^{23}$ particles (atoms, molecules or ions) which is also known by the name Avogadro's number.

For example: 1 mole of $O_2$ molecule contains $6.022\times 10^{23}$ molecules of oxygen.

1 mole of $He$ contains $6.022\times 10^{23}$ atoms of helium.
