Question

Calculate the no of electron in 100 gm co2

Answer 1

Explanation:

no. of electrons in C = 6

no. of electrons in o = 8

no. of electrons in co2 = 6+16= 22

no. of moles of co2 in 100g

= 100/44 = 25/11moles

no. of co2 in 25/11 moles

= 25/11× 6.022×10^23

total no. of electrons

= 25/11 × 6.022×10^23 × 22

= 25 × 6.022 ×10^23 ×2

= 50 ×6.022×10^23

= 30.11 × 10^24

= 3.01 × 10^25

= 3 × 10^25 (approx )

Answer 2

Answer:

6 ele of C + 16 of O2 = 22 ele per molecule of CO2  

6.022 x 10²³ molecule = 44g mol⁻¹

moles of CO2 = 100 / 44

= 2.27 mol  

electron = 22 x 2.27 x 6.022 x 10²³  

electron will be = 3x 10²⁵
