Question

Number of representative particles in 0.250 mol silver

Answer 1

A mole is just a specific number = 6.022 x 10^23 {actually this is approximately the number}. So one mole of a particular thing is 6.022 x 10^23 of those things. In a 0.250 mole silver = 0.250 (6.022 x 10^23) silver = 1.506 x 10^23 silver.

Answer 2

Answer: The number of representative particles in the given amount of silver are $1.506\times 10^{23}$

Explanation:

We are given:

Moles of silver = 0.250 moles

According to mole concept:

1 mole of an element contains $6.022\times 10^{23}$ number of atoms

So, 0.250 moles of silver will contain = $(0.250\times 6.022\times 10^{23})=1.506\times 10^{23}$ number of atoms.

Hence, the number of representative particles in the given amount of silver are $1.506\times 10^{23}$
