Question

total number of electrons in 440g of co2​

Answer 1

Answer:

44g Co2=1mol

no.of moles in440gCo2

=440÷44=10moles

no.of molecules in one mole of Co2=avagadro no.

=6.022×10^23 molecules

=>10moles of Co2 contains

10×(6.022×10^23) molecules

one Co2 molecule contains 6+(2×8)=22 electrons

=>10 mol Co2 contains 10×(6.022×10^23)×22 electrons.
