Answer:
4.52 × 10^23 atoms
Explanation:
Concept being tested: Moles and Avogadro's number
From the question we are given;
- Number of moles of Zinc = 0.750 moles
We are required to calculate the number of atoms of Zinc
- In order to answer the question, we need to know that a mole of an element contains atoms equivalent to the Avogadro's number.
- The Avogadro's number is 6.022 × 10^23.
Therefore;
1 mole of Zinc = 6.022 × 10^23 atoms
To calculate the number of atoms we need to multiply the number of moles with the Avogadro's constant.
= 0.750 moles × 6.022 × 10^23 atoms
= 4.52 × 10^23 atoms
Therefore; 0.750 moles of Zinc contains 4.52 × 10^23 atoms
