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.
What else can I help you with?
Does a mole of carbon atoms have three times greater then helium?
No, a mole of carbon atoms has the same number of atoms as a mole of helium atoms (Avogadro's number, which is about 6.022 x 10^23 atoms). The difference lies in their atomic masses, as carbon atoms are heavier than helium atoms.
One mole of atoms represents how many atoms?
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.
Does mole of carbon atoms have a different mass than a mole of sulphur atoms?
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.
15.Why does one mole of carbon atoms have a smaller mass than one mole of sulfur atoms?
Because the sum of protons, neutrons and electrons masses in sulfur atom is higher than in a carbon atom.
Which has more atoms 2 moles of helium or 1 mole of gold?
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.
Which would have a higher mass a mole of K atoms or a mole of Au 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.
Why does one mole of carbon atoms have a smaller mass than one mole of sulfur atoms?
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.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
A mole of any substance contains Avogadro's number of particles (6.02 x 10^23). The molar mass of copper is less than that of lead, so a mole of copper atoms weighs less than a mole of lead atoms, despite both containing the same number of atoms.
Which would contain more atoms a mole of K atoms or a mole of Au 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.
Does a mole of carbon atoms have three times greater then helium?
No, a mole of carbon atoms has the same number of atoms as a mole of helium atoms (Avogadro's number, which is about 6.022 x 10^23 atoms). The difference lies in their atomic masses, as carbon atoms are heavier than helium atoms.

Is 1.11 mol of Pt more or less than 6.022 x 1023 atoms and why?
6.022 x 1023 atoms comprise just about 1 mole. 1.11 moles is greater than 1 mole.
Why is one mole of aluminum larger than one mole of copper?
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.
How can a mole of any substance contain the same number of particles?
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.
