How many moles of c atoms are in 1 mol of sucrose (c12h22o11)?

Use dimensional analysis to solve problems like these.

1 mol C12H22O11 * 12 mol C atoms / 1 mol C12H22O11 = 12 mol of C atoms

Alternatively, you can also think of Sucrose as a molecule with 12 atoms of Carbon, 22 atoms of Hydrogen, and 11 atoms of Oxygen. Each of the atoms represent one mole and since you have 12 Carbon atoms, it would equal to 12 moles of Carbon atoms.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
