<u>Ans :</u>4.5 * 10²³ molecules
<u>Given:</u>
Moles of CH4 = 0.75
<u>To determine;</u>
The number of molecules of CH4 in 0.75 moles
<u>Explanation:</u>
1 mole of CH4 contains Avogadro's number i.e. 6.023*10²³ molecules
Therefore, 0.75 moles would correspond to :
= 0.75 moles * 6.023*10²³ molecules/1 mole
= 4.5 * 10²³ molecules
