Question

Calculate the number of electrons in 100 gm of co2

Answer 1

Answer:

2200

Explanation:

c=carbon

carbon's mass=12

o2=oxygen

oxygen's mass=8*2

                        =16

total=12+16

      =28

now,In a neutral atom, atomic number represents the number of protons inside the nucleus and equal number of electorns around it. Therefore, the number of total electrons in molecule of CO2 = electrons present in one carbon atom + 2 × electrons present in one oxygen atom. = 6 + 2 × 8 = 22

then, electron in 1 molecule=22

so 1x=22

then 100x=22*100

               =2200
