Same reason a dozen is used to count 12 eggs. This is the agreed on unit that chemist's use. Iron is 55.85 grams/mole, which means that 6.022 X 1023 atoms are in this mass iron. Now carbon is 12.01 grams/mole with the same number of atoms in that mass. Rather like a dozen eggs weighing different amounts because some are labeled small, medium or large yet all are still 12 eggs in the dozen.
The mole equals 6.022*10 to the 23 power, there for it is easier to count a mole than an atom.
Due to the fact that atoms are very small for experimental purposes, moles were decided to be used so therefore, mole is used to as a unit for meansuring atom for experimental purposes

true
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
Because the sum of protons, neutrons and electrons masses in sulfur atom is higher than in a carbon atom.
6.0221 x 1023 atoms/molecules/entities make up one mole. It is known as Avogadro's number. This is a consequence of the definition of one mole, rather than being the cause of the definition of a mole. It is not necessary to know this number for the majority of calculations using moles.
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.
Sugar is composed of 22 atoms of hydrogen, 12 atoms of carbon as well as 11 atoms of oxygen
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
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.

That's just the way it was set up. 6.022x1023 atoms of an element equals one mole of that element. 6.022x1023 molecules of a compound equals one mole of that compound. Remember, a mole does not measure weight. One mole of hydrogen weighs a lot less than a mole of acetic acid. A mole just means 6.022x1023 particles, whether those particles are atoms, ions, molecules, or ionic compounds.
For the same reason that one dozen pencils has a smaller mass than one dozen bricks. Each atom of carbon weighs less than each atom of sulfur, and a mole of each has the same number of atoms, so a mole S will weigh more than a mole C.
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
6.022 x 1023 atoms comprise just about 1 mole. 1.11 moles is greater than 1 mole.
Because the sum of protons, neutrons and electrons masses in sulfur atom is higher than in a carbon atom.
An atom is a component of matter; mole is a unit for the amount of substance in SI. Of course a mole of atoms is bigger than a single atom.

A mole is a number of atoms. Because atoms are very small, rather than counting individual atoms, it is easier to count a mole of atoms. A mole of atoms is a very large number of atoms: 6.02 x 1023 atoms.Moles are often used to talk about amounts of chemicals. Because different elements weigh different amounts, using the weight of a chemical isn't always the best way to measure the number of atoms or molecules in a sample. Moles are commonly used in this way to talk about the concentration of a solution (for instance, the number of moles of dissolved substance per liter of solution is called molarity).See the Related Questions to the left for more information.
