Question

1.03 moles of CHg contains how many hydrogen atoms?

Answer 1

1.03 moles of CH₄ contain approximately
`\(2.49 * 10^(24)\)` hydrogen atoms, calculated using Avogadro's number and the molecular composition of methane.

To determine the number of hydrogen atoms in 1.03 moles of CH₄, use Avogadro's number. One mole of any substance contains
`\(6.022 * 10^(23)\)` entities (atoms, molecules, etc.). In CH₄, there are four hydrogen atoms per molecule.

`\[ \text{Number of moles of CH}_4 = 1.03 \, \text{mol} \]`

`\[ \text{Number of molecules of CH}_4 = 1.03 * 6.022 * 10^(23) \]`

Since each molecule of CH₄ contains four hydrogen atoms:

`\[ \text{Number of hydrogen atoms} = 4 * 1.03 * 6.022 * 10^(23) \]`

After calculations, the result is approximately
`\(2.49 * 10^(24)\)` hydrogen atoms.
