2423Answer
Explanation
Given:
Mass of copper = 154 kg
Convert kg to gram by multiplying by 1000
154 kg x 1000 = 154000 grams
From Avogadro's constat, 1 mole of any substance contains 6.022×10²³ atoms
The molar mass of copper, that is, the amount of mass that copper contains in one mole, is 63.546 g/mol. So, 154000 g of copper are contained in:
[tex]154000g\times\frac{1\text{mol}}{63.546\text{ g}}=2423.441287\text{ mol}[/tex]Since 1 mole of copper contains 6.022×10²³ atoms,
Therefore 2423.441287 moles of copper will contains:
