Answer:
12 g
Explanation:
From the question given above, the following data were:
Number of atoms = 6.02×10²³ atoms
Mass of ₆C¹² =?
From Avogadro's hypothesis,
1 mole of any substance contains 6.02×10²³ atoms. This implies that 1 mole of ₆C¹² also contains 6.02×10²³ atoms i.e
1 mole of ₆C¹² = 6.02×10²³ atoms
Recall
From the period,
1 mole of ₆C¹² = 12 g
Thus,
12 g of ₆C¹² = 6.02×10²³ atoms
Therefore, 12 g of ₆C¹² contains 6.02×10²³ atoms
