You will need to specify the mass of C6H6 in order to calculate a number of moles.
If you know the mass, the general formula is:n=m/M,
where n is the number of moles, m the mass of C6H6 and M the molar mass (78.11g/moles)
In a mol of a substance there are 6.022E23 molecules. There are 12 atoms in each molecule of C6H6 (benzene). Thus, in a mole of benzene there are 6.022E23 * 12 atoms.
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.
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
there are two Carbon Atoms and six Hydrogen atoms
In a mol of a substance there are 6.022E23 molecules. There are 12 atoms in each molecule of C6H6 (benzene). Thus, in a mole of benzene there are 6.022E23 * 12 atoms.
Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
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.
1molecule of C2H6 contains 2 carbon atoms
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.
The answer is 2,17 moles carbon.
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
