The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).

In CARBON material , it has also 6.022*10^(23) atoms in one mole of it , that is equivalent to 12 grams as it has atomic weight 12amu.

Why use 12 grams? This is the theoretical atomic mass of the Carbon-12 isotope (6 protons and 6 neutrons). This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

The mole was defined by International Bureau of Weights and Measures as "the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12." Thus, by that definition, one mole of pure 12C had a mass of exactly 12 g.

For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unitis TINY.

One mole (abbreviated mol) is equal to the number of atoms in 12 grams of carbon-12; this number is referred to as Avogadro's number and has been measured as approximately 6.022 x 1023.

Glucose has six carbons, twelve hydrogen, and six oxygen atoms. Using the periodic table, the atomic weight of C, H, and O are obtained. So the molar mass of C6H12O6 is 72.06 g + 12.096 g + 96.00 g = 180.156 g or 180.16 g (right number of significant figures).

1) What is the mass of 1 atom of carbon? 1 molecule of glucose contains 6 atoms of C, 12 atoms of H, and 6 atoms of O • 1 mole of glucose contains 6 moles of C atoms, 12 moles of H atoms, and 6 moles of O atoms.

The molar mass of carbon is 12.011 grams/mol. Thus there is half a mole of carbon in a 6 gram diamond. Avogrado's number allows us the calculate that there is thus 3.01*10^23 atoms of carbon in said diamond. This assumes the diamond is completely pure.

For every molecule of C12H22O11, there are 12 carbon atoms, aka 1:12. This means that 0.1 mole C12H22O11 is 12*0.1=1.2 mole carbon. One mole is around 6.022 * 10^23 atoms.

The carbon-12 atom has six protons and six neutrons in its nucleus for a mass number of 12. Since the nucleus accounts for nearly all of the mass of the atom, a single proton or single neutron has a mass of approximately 1 amu.

A dozen CO2 molecules have one dozen carbon atoms and two dozen oxygen atoms. A million CO2 molecules have one million carbon atoms and two million oxygen atoms. A mole of CO2 molecules (we usually just say “a mole of CO2”) has one mole of carbon atoms and two moles of oxygen atoms.

One mole of carbon still has 6.022 × 1023 carbon atoms, but 98.89% of those atoms are carbon-12, 1.11% are carbon-13, and a trace (about 1 atom in 1012) are carbon-14.
