For this problem you don't need the Atomic Mass of the element. If you want to convert moles to atoms, you need to take the number of moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for units to cancel.
2.50 moles H × (6.02 × 1023 atoms) = 1.51 ×1024 atoms H
If you mean in 2.5 moles of the element H, then it will be 2.5 moles H x 6.02x10^23 atoms/mole = 1.5x10^24 atoms. If you mean 2.50 moles of hydrogen gas (H2), then it will be twice that or 3x10^24 atoms.
2.5 mol of uranium = 2,5 x Avogadro's number = 15,055354475.1023 atoms
1 mole atoms U = 6.022 x 1023 atoms
2.50mol U x 6.022 x 1023 atoms/1mol = 1.51 x 1024 atoms U
2.50 mole of H2 contains 5.0 moles of hydrogen atoms (H),
which are 5.0 * 6.02*10+23 atoms (particles) = 3.0*1024 atoms H
2.5 moles × (6.02 × 1023) = 1.51 × 1024 atoms
15,055354475.1023 uranium atoms
If 2,5 is grams: 6,325.1021 atoms.
338.10e23 hydrogen atoms
The answer is 175,08.10e23 atoms.
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
There are 40 moles of hydrogen atoms in 4 moles of cyclopentane because each molecule of cyclopentane contains 10 hydrogen atoms (as indicated by the molecular formula C5H10).
360 g H2O x 1 mol/18g H2O x 6.02x10^23 H2O molecules/mol x 2 H atoms/molecule = 2.4x10^25 hydrogen atoms.
338.10e23 hydrogen atoms
0.63 mol of (NH4)2SO4 contain 3,978.10e23 hydrogen atoms.
Avagadro's number = 6.022 × 1023 atoms/mol0.5 mol × (6.022 × 1023) atoms/mol = 3.011 ×1023 atoms
The answer is 175,08.10e23 atoms.
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
there are 1.30e25 Hydrogen atoms in 2.70 mol Ammonium Sulfide
1 molecule of hydrogen contains 2 hydrogen atoms,so 1 mole of hydrogen consists of 2 moles of atoms.
1.64 x 1025
There are 40 moles of hydrogen atoms in 4 moles of cyclopentane because each molecule of cyclopentane contains 10 hydrogen atoms (as indicated by the molecular formula C5H10).
360 g H2O x 1 mol/18g H2O x 6.02x10^23 H2O molecules/mol x 2 H atoms/molecule = 2.4x10^25 hydrogen atoms.
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
