Question

Why do we have to multiply the number of electrons with Avogadro's number and number of moles to get the total number of electrons?

Answer 1

Answer:

First we have to find out the no. of moles with the formula

TOTAL MASS/GIVEN MASS

Then we will multiply it with Avagadro's no.(also called NA) to find the no.of particle of that element in calculated no. of moles .

CALCULATED NO. OF MOLE *AVAGADRO'S NO. =NO. OF PARTICLE PRESENT

Then obviously , we will multiply the no.of particle present with no.of electron present in that specific particle to find total of no. of electron present in that particle

NO. OF PARTICLE PRESENT * NO. OF ELECTRON PRESENT IN UNITY OF THAT PARTICLE = NO . OF ELECTRON PRESENT IN GIVEN AMOUNT OF PARTICLE

Answer 2

Answer:

avagadro,s number is apropotion that relates molar mass on an atomic scale to physical mass on human scale.

avagadro,s number is defined as the number of elementary particles such as molecules, atoms, compounds etc. per mole of a substance it is equal to 6.022 multiply by 10 exp 23 per mole and is expressed an the symbol NA
