How many atoms of hydrogen are found in 2.48 mol of propane, C3H8?

Someone can explain to me. Thanks

  • chemistry -

    How many molecules do you have in 2.48 moles C3H8? There are 6.022 x 10^23 molecules in 1 mol; therefore, there must be 2.48 x 6.022 x 10^23 molecules in 2.48 moles. That is 1.49 x 10^24 molecules. Then each molecule C3H8 has 8 H atoms so total number of H atoms must be 1.49 x 10^24 x 8 = ??. Check my arithmetic.
