What is the mass in grams of 1.204 x 1024 atoms of carbon?

24g of carbon

Explanation:

From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 atoms. This gives us a background understanding that 1mole of carbon also contains 6.02x10^23 atoms.

1 mole of carbon = 12g

If 12g of carbon contains 6.02x10^23 atoms,

then Xg of carbon will contain 1.204 x 1024 atoms i. e

Xg of carbon = (12x1.204x10^24) / 6.02x10^23 = 24g

Therefore, 24g of carbon contains 1.204x10^24 atoms
