Question

Calculate the number of molecules in 0.75 moles of CH₄. x 10²³ molecules

Answer 1

Ans :4.5 * 10²³ molecules

Given:

Moles of CH4 = 0.75

To determine;

The number of molecules of CH4 in 0.75 moles

Explanation:

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
