Answer:
1.385 × 10²³ atoms of calcium
Explanation:
Given data:
Number of moles of calcium = 0.23 mol
Number of atoms = ?
Solution:
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.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For 0.23 mole of calcium:
one mole = 6.022 × 10²³ atoms of calcium
0.23 × 6.022 × 10²³ atoms of calcium
1.385 × 10²³ atoms of calcium
