Parth Joshi 7 years, 6 months ago

Mass=2.2mg ,moles of (CO2)=mass÷molarmass = 2.2÷44 ×100=5(CO2) mol. 5mol of Co2=5 na molecules

Alisha Bhagat 7 years, 6 months ago

44g CO2 contains 6.022×10^23 molecules of CO2 =6.022×10^23 atoms of C + 12.044×10^23 O atoms Therefore 44g CO2 = 12.044×10^23 O atoms. Now, 1g CO2 contains 12.044×10^23/44 O atoms So 2.2×10^-3g CO2 contains (12.044×10^23/44)×2.2×10^-3 =11.022×10^19 O atoms. I hope it's clear
