Question

0.1 mole of hydrogen - Calculate the number of particles in it.

Answer 1

Answer ⇒ 6.022 × 10²² Particles.

Solutions ⇒

No. of moles of Hydrogen = 0.1 mole.

∵ No. of particles = No. of moles × Avogadro's number.

∴ No. of Particles = 0.1 × 6.022 × 10²³

= 6.022 × 10²² Particles.

Hence, the number of the Particles in 0.1 mole of the Hydrogen gas is 6.022 × 10²².

Hope it helps.

Answer 2

To calculate the number of Hydrogen

particles ,let us discuss about Avogadro

number Na= 6.023*10^23

Avogadro number is the number of atoms

/particles present in one mole of substance.

so,according to question 0.1 mole of Hydrogen

is given.

number of particles present= 0.1*Na

= 0.1*6.023*10^23

=6.023*10^22
