Question

what is mole? find no. of electrons in 1.4g CH4 ​

Answer 1

Hey dear ur answer is here...

The mole is the unit of measurement for amount of substance in the International System of Units. A mole of a substance or a mole of particles is defined as exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons. In short, for particles 1 mol = 6.02214076×10²³.

total number of electrons present in 1.6 g of methane = 6.022×1022

molecules of methane contain electrons 

6.022×10²³×10

=6.022×10²³.
