Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.

How many atoms of hydrogen are in 0.200M of propane?

Propane has a chemical formula of C3H8, which means there are 8 hydrogen atoms in each molecule of propane. To calculate the number of hydrogen atoms in 0.200M of propane, you would multiply the concentration (0.200 mol/L) by Avogadro's number (6.022 x 10^23 atoms/mol) and by the number of hydrogen atoms in a molecule of propane (8). This would give you the total number of hydrogen atoms present.
