Question

If one mole of carbon atoms weights 12 gm . What is the mass of 1 atom of carbon?​

Answer 1

Answer:

A mole is defined as exactly equal to 6.022×1023 atoms. So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g. Hence, the mass in grams of 1 atom of carbon is 1.993×10−23g .

Answer 2

Answer:

If one mole of carbon atoms weighs 12 g, then the mass of 1 atom of carbon will be $1.993*10^{-23}$g.

Explanation:

Weight of 1 mole of carbon = 12 g.

1 mole of any substance contains $6.022 * 10^{23}$ particles.

∴1 mole of carbon contains $6.022 * 10^{23}$ atoms.

So 12 g should contain $6.022 * 10^{23}$ atoms.

∴ Weight of 1 atom = $\frac{12}{6.022 * 10^{23}}$

                                = $1.993*10^{-23}$g

If one mole of carbon atoms weighs 12 g, then the mass of 1 atom of carbon will be $1.993*10^{-23}$ g.
