Quinine has the chemical formula C20H24N2O2. To determine the number of moles of hydrogen in 1.8 moles of quinine, we note that each molecule of quinine contains 24 hydrogen atoms. Therefore, in 1.8 moles of quinine, there are 1.8 moles × 24 moles of hydrogen = 43.2 moles of hydrogen.
Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
The nunber of moles of oxygen is 2,5.
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.
To find the number of moles of S in 22.9 g of C6H10S, you need to first calculate the molar mass of C6H10S, which is 126.23 g/mol. Then, divide the given mass by the molar mass to find the number of moles. For S in C6H10S, the molar mass contribution is 32.06 g/mol, so 22.9 g is equivalent to 0.717 moles of S.
To find the number of moles, you need to first calculate the molar mass of C6H10S: Carbon has a molar mass of 12.01 g/mol, hydrogen has a molar mass of 1.01 g/mol, and sulfur has a molar mass of 32.07 g/mol. Adding these up gives a molar mass of 114.17 g/mol for C6H10S. Then, divide the given mass by the molar mass to find the number of moles: 225 g / 114.17 g/mol ≈ 1.97 moles.
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
Seventeen moles of hydrogen correspond to 204,75.10e23 atoms.
There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
0,565 moles
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 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
