Question

how many particles are represented in 0.25 moles of an element

Answer 1

Particle in 1 mole of an element = 6.022*10^23

Particle in 0.25mole of an element = 6.022*10^23 * 0.25

=1.5055*10^23

Answer 2

Given: 0.25 moles of an element.

To find: We have to find the number of particles.

Solution:

To determine the number of particles of an element we have to follow the below steps-

One mole of any element always contains $6.023×10^{23}$ number of particles.

One mole of an element contains $6.023×10^{23}$ number of particles.

0.25 mole of an element contains $6.023×10^{23}×0.25=1.5×10^{23}$ number of particles.

0.25 mole of an element contains $1.5×10^{23}$ number of particles.
