The number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
The given parameters;
- <em>mass of the reacting sodium = 0.231 g</em>
- <em>1 mole of an atom = 6.02 x 10²³ atoms</em>
- <em>the atomic mass of sodium is 23 g/mol</em>
The number of moles of 0.231 g of sodium available is calculated as;
The number of atoms of 0.01 mole of sodium available is calculated as;
1 mole ---------- 6.02 x 10²³ atoms
0.01 ----------------- ?
= 0.01 x 6.02 x 10²³ atoms
= 6.02 x 10²¹ atoms.
Thus, the number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
