1 mol of any substance=6.022 10²³ particles
Now, we calculate the number of moles of this sample:
1 mol----------------------------6.022 10²³ molecules
x-----------------------------------2.0 10²² molecules
x=(1 mol 2.0 10²² molecules) / (6.022 10 ²³ molecules)=0.033 moles=
=3.3 10⁻² moles.
Answer: 3.3 10⁻² moles.
