Question

answer the question

calculate the total number of electrons present in 1 mole of Methane ​

Answer 1

Answer:

(i) Molecule of CH4 (methane) contains electron = 10. Therefore 1 mole (6.022 x 1023 atoms) contains electron = 6.022 x 1024

(ii) a) 1g atom of 14C = 14g = 6.022 x 1023 atoms = 6.022 x 1024 x 8 neutrons. ...

(iii) a) 1 mol of NH3 = 17g NH3 = 6.022 x 1023 molecules of NH3 = (6.022x1023)(7 + 3) proton = 6.022 x 1024 protons.
