how many hydrogen atoms are present in 2-methylbutane?
154533
Count the number of carbon atoms in total in a molecule of 2-methylbutane (5), and the total number of hydrogen atoms (12), so the molecular formula of 2-methylbutane is the same as that for pentane, that is, C5H12, therefore pentane and 2-methylbutane are structural isomers.

Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. Thus we must multiply 6.022 * 1023 by 2 to calculate the number of individual atoms present in 1 mole of H2. We find our answer to be 1.2044 * 1024.

As you can see from its molecular formula, there are two Hydrogen atoms in a molecule of Hydrogen. In one mole of Hydrogen gas,there would be6. 02×10^23molecules. In every molecule, there are two atoms, so the number of atoms in 1 mol of hydrogen would be (6.02×10^23)×2=12.04×10^23 atoms.
