Question

give the number of carbon and hydrogen atoms in 2 moles of methane?

Answer 1

There are 8 hydrogen atoms in 2 moles of methane
One mole is equal to 6.022 x 10²³.
Therefore, in 2 moles of methane molecules, there are 4.817 x 10²⁴ hydrogen atoms in 2 moles of methane

There are 2 carbon atoms in one molecule of methane
One mole is equal to 6.022 x 10²³.
Therefore, in 2 moles of methane molecules, there are 1.204 x 10²⁴ carbon atoms in 2 moles of methane molecules. molecules.
