Question

In a full stop, 2 mg carbon is present. Calculate no. Of carbon atoms

Answer 1

Answer:

Given wt. of Carbon in a full stop = 2mg

Mol. wt. of carbon = 12g = 12,000mg

1 mole Carbon contains  $N_{A}$  atoms of carbon

So,

2mg Carbon contains  $\frac{2}{2000}$ $N_{A}$ atoms

∴The answer is 6.022 x $10^{20}$
