How many moles of sodium atoms do you have if you have 5.60 ~
Papessa [141]

Answer:

0.93 mol

Explanation:

Given data:

Number of moles of Na atom = ?

Number of atoms = 5.60× 10²³

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

5.60× 10²³ atoms ×  1 mol / 6.022 × 10²³ atoms

0.93 mol

How many moles of c atoms are in 1 mol of sucrose (c12h22o11)?
Damm [24]

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.
