Question

Calculate the number of particles (atoms)in 0.1 mole of carbon atoms ​

Answer 1

Answer: 6.023\times 10^{22}6.023×10

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}6.023×10

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}6.023×10

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}

1

6.023×10

23

×0.1=6.023×10

22

particles of carbon

Thus 6.023\times 10^{22}6.023×10

22

particles are present in 0.1 mole of carbon atoms
