Question

Calculate the number of particles in 0.1 mole of carbon atoms.

Answer 1

according to Avagadro number
.


1mole of carbon = 12g = 6.022×10^23


so

0.1 moles =0.1×6.022×10^23

6.022×10^22

Answer 2

Answer:  $6.023\times 10^{22}$ particles

Explanation:-

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

Standard condition of temperature (STP)  is 273 K and atmospheric pressure is 1 atmosphere respectively.  

1 mole of carbon atoms contain = $6.023\times 10^{23}$ particles of carbon

Thus 0.1 mole of carbon atoms contain = $\frac{6.023\times 10^{23}}{1}\times 0.1=6.023\times 10^{22}$ particles of carbon

Thus $6.023\times 10^{22}$ particles are present in 0.1 mole of carbon atoms.
