How many hydrogen atoms are found in one mole of methane molecules?

Short Answer

Expert verified
The number of hydrogen atoms in one mole of methane molecules is \(2.4088 \times 10^{24}\)

Step by step solution

01

Define the composition of methane

In one molecule of methane (CH4), there are 4 hydrogen atoms.
02

Determine the number of methane molecules in a mole

One mole of any substance contains \(6.022 \times 10^{23}\) entities. This is known as Avogadro's number. Therefore, one mole of methane contains \(6.022 \times 10^{23}\) methane molecules.
03

Calculate the number of hydrogen atoms

Since every methane molecule contains 4 hydrogen atoms, to find the total number of hydrogen atoms, you just need to multiply the number of methane molecules by 4. Therefore, \(6.022 \times 10^{23}\) methane molecules x 4 = \(2.4088 \times 10^{24}\) hydrogen atoms.
