Question

calculate total number of electrons present in 1 mole and 8 gm of methane​

Answer 1

number of electrons is 3.011"10to power of-23

metane =CH4

molecular weight=12*1+4*1

=16 = 1 mole

1 mole is 16 gm

____mole is equal to 8 gm

so 8 gm has half mole by cross multiplication

number of electrons is 3.011"10to power of-23
