Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
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.
4,2.10e25 H atoms
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
There are 24 moles of hydrogen in 4 moles of CH4 because each molecule of CH4 contains 4 hydrogen atoms. Therefore, you have 24 moles x 6.022 x 10^23 atoms/mol = 1.4448 x 10^25 atoms of hydrogen.
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.
There are 12 atoms of hydrogen in 3 moles of CH4. CH4 consists of one carbon atom and four hydrogen atoms. Since each mole of CH4 has 4 hydrogen atoms, 3 moles would have 3 * 4 = 12 hydrogen atoms in total.
Just moles against the ratio of hydrogen atoms in compound then against Avogadro's number. Like this 0.09 moles H2SO4 (2 moles H/1 mole H2SO4)(6.022 X 10^23/1 mole H) = 1.1 X 10^23 hydrogen atoms
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
4,2.10e25 H atoms
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
One molecule has four H atoms.So two moles have 8 moles
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
