Let's see.
1 mole K atoms = 6.022 X 1023 atoms * 19 electrons
= 1.144 X 1025 electrons in one mole potassium
-------------------------------------------------------------
1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons
= 4.757 X 1025 electrons in one mole gold
------------------------------------------------------
A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
A mole of any substance contains the same number of atoms, which is approximately 6.022 x 10^23. Therefore, a mole of silver atoms and a mole of gold atoms would both contain the same number of atoms.
There are 1 mole of nitrogen gas molecules contain 2 nitrogen atoms. Therefore, 0.25 mole of nitrogen gas would contain 0.25 * 2 = 0.5 moles of nitrogen atoms.
The number of electrons in a mole of any substance would be Avogadro's number times its atomic number (if an element) or times the sum of the atomic numbers of its molecule (if a compound) So, since the atomic number of Al is 13, the number of electrons is (6 X 10^23) X 13 = 78 X 10^23. Give or take a few.
One!The long and short of it is... one!Gold does not really form molecules but is made up of a lattice of gold atoms: these could be interpreted as "mono-atomic molecules", in short... atoms!AnswerOne, it is an element unique unto itself

One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
Ammonium chloride has the formula of NH4Cl. Thus, in each mole there are 4 moles H, 1 mole N and 1 mole Cl for a total of 6 moles of atoms. Then 6.02x10^23 atoms/mole x 6 moles = 3.6x10^24 atoms.
Aluminum is number 13 on the periodic table so each aluminum atom has 13 protons and 13 electrons.One mole of anything has is 6.022x1023 atoms (Avogadro's number)So 1 mole of aluminum has 13x6.022x1023 electrons
6.0221415 x 10^22 atoms
A mole of Au atoms would have a higher mass compared to a mole of K atoms because gold (Au) atoms have a larger atomic mass than potassium (K) atoms. The molar mass of a substance is determined by adding the atomic masses of the individual atoms in the mole.
