Question

calculate the number of electrons in 1.6 gram of Methane ch4​

Answer 1

Answer:

CH4

it is neutral

so by adding their atomic no. we will get total no. of e- in methane

6+1x4=10

so their are 10e- in CH4.

we know...

moles =wt./Mwt.

moles =1.6/16=0.1

molecules=moles x NA

(NA is avagadro constt.

and its value is 6.022x10^23)

molecules= 0.1x6.022x10^23

=0.6022x10^23

Now we know, 1molecule of methane contain 10e-

so 0.6022x10^23 molecules contain --> 10x0.6022x10^23 e-

= 6.022x10^23 e-
