How many methane molecules are in 4.32 grams of methane?

1.6254‬ x 10^23 molecules

Explanation:

Step 1:

Divide Mass by Molar Mass to get moles of substance

n = 4.32 / 16

n = 0.27 moles of Methane

Step 2:

Calculated no of moles Multiply by Avogadro's Number

No of molecules = moles x Avogadro's Number

No of molecules of methane = 0.27*6.02 x 10^23

No of molecules of methane = 1.6254‬ x 10^23 molecules

yes
