Question

b. The number of carbon atoms in 12
mg of his homework writting​

Answer 1

According to the molar concept ,there will be always 6.023×10²³ (avgadro's number) atoms.

And according to the mathematical calculations we came to know that one mole of carbon weighs approximately 12 grams.

So,

12 grams of carbon = 6.023 × 10²³

12000 mg of carbon = 6.023 ×10 ²³

1 mg of carbon = 6.023 × 10²³ / 12000

12 mg of carbon = 6.023 × 10²³ × 12 /12000 = 6.023 × 10^20

So, there will be 6.023 × 10^20 atoms in 12 mg of carbon. (Answer)
