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.
6.02x10^23
A mole of iron has more mass than a mole of helium, even though they contain the same number of atoms, because 1 atom of iron has a greater mass than 1 atom of helium. It is similar to why 1 dozen bricks has a greater mass than 1 dozen roses. There are 12 items in each case, but 1 brick has a greater mass than 1 rose.
It is more because 1 mol of platinum is 6.022 X 10^23 atoms, therefore 1.11 moles of platinum would be more.

2 moles of helium contain more atoms than 1 mole of gold. Since 1 mole of any substance contains Avogadro's number of atoms (approximately (6.022 \times 10^{23})), 2 moles of helium would have about (1.204 \times 10^{24}) atoms, while 1 mole of gold has approximately (6.022 \times 10^{23}) atoms. Therefore, 2 moles of helium have double the number of atoms compared to 1 mole of gold.
2 moles of HCl contain 2 moles of hydrogen atoms since each HCl molecule has one hydrogen atom. In contrast, 1 mole of NH3 contains 3 moles of hydrogen atoms because each NH3 molecule has three hydrogen atoms. Therefore, 1 mole of NH3 has more hydrogen atoms than 2 moles of HCl.
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
6.02x10^23
One mole is approximately equal to Avogadro's Number of atoms, 6.023 times 10 to the 23rd power or 6.023E23, where "E" stands for "10 raised to the power of". So, 1.11 mole would be greater.
A mole of iron has more mass than a mole of helium, even though they contain the same number of atoms, because 1 atom of iron has a greater mass than 1 atom of helium. It is similar to why 1 dozen bricks has a greater mass than 1 dozen roses. There are 12 items in each case, but 1 brick has a greater mass than 1 rose.
Since one mole of any substance contains 6.0225 x 1023 atoms (for elements) or molecules (for compounds), a hundredth of a mole would contain 6.0225 x 1021 atoms or molecules.It could also be called a "centimole" but I've never heard anybody use that unit. The more common unit is a millimole, which is one thousandth of a mole.See the Related Questions to the left for more information.
It is more because 1 mol of platinum is 6.022 X 10^23 atoms, therefore 1.11 moles of platinum would be more.
No, 0.25 moles of O2 contains fewer molecules than 0.25 moles of NH3. This is because O2 is a diatomic molecule (Oxygen exists as O2), whereas NH3 is a triatomic molecule (Nitrogen exists as NH3). Thus, NH3 has more atoms per molecule compared to O2.
They both have the same number of atoms. The weight is different
