One mole of methane (CH₄) contains a total of 3 * 10²⁴ atoms.

Question

Quizplus · Accepted Answer

This is true. A mole of any substance contains Avogadro's number of atoms or molecules, which is approximately 6.022 x 10^23. One molecule of methane contains one carbon atom, four hydrogen atoms, and no fluorine or sulfur atoms. Therefore, one mole of methane must contain 6.022 x 10^23 carbon atoms, 4 x 6.022 x 10^23 hydrogen atoms, and 0 fluorine or sulfur atoms. This gives a total of 1 carbon atom and 4 hydrogen atoms, or a total of 5 atoms per molecule of methane. Multiplying by Avogadro's number gives a total of 3 x 6.022 x 10^23 atoms in one mole of methane, or approximately 1.8066 x 10^24 atoms.
