Question

Calculate total number of valence electrons present in 1.42gm of methane.
​

Answer 1

Answer:

4.239×10^23

Explanation:

no.of mol of methane = 1.42/16 = .0.088

no.of molecules of methane = 0.088×6.022×10^23

1 molecule of methane contains 8 Valence electrons

hence , no of Valence electrons =

= 0.088×6.022×10^23×8

= 4.239 ×10^23
