The number of atoms is 52,63.10e23.
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
We have 2.1 moles of H3PO4 However , there are three hydrogen atoms. So this makes for 3 x 2.1 = 6.3 moles of hydrogen atoms. Further, hydrogen exists as the diatomic molecule 'H2'. So a 'free' hydrogen molecules of H2 we have 6.3 / 2 = 3.15 moles(H2)
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
One molecule has four H atoms.So two moles have 8 moles
4,2.10e25 H atoms
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
To find the number of moles of H atoms in C2H4Cl2, we first need to calculate the molar mass of C2H4Cl2. The molar mass is 98.96 g/mol. Next, we calculate the moles of C2H4Cl2 in 47.2742 grams by dividing the mass by the molar mass which is 0.478 moles. Since there are 4 H atoms in one molecule of C2H4Cl2, multiply the moles of C2H4Cl2 by 4 to find moles of H atoms which is 1.913 moles.
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================

.1146g of mass of Unknown and 12.00ml of NaOH. Find the moles of acidic H atoms
5.00 moles H x 1 mole C2H4O2/4 moles H = 1.25 moles of C2H4O2 present.
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
One molecule has four H atoms.So two moles have 8 moles
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
divide the mass of the hydrogen by the molar mass.
