As we know,
No. of molecules =no. of moles *Avogadro Number
No. Of moles would be=No. of molecules /Avogadro number
No. Of moles = 1/6.022*10^23. [Avogadro number =6.022*10^23]
We will not do calculations at this point, we will later solve this
And we also know,
No. of moles = mass of compound /molecular weight of the compound
And we have to find mass of compound, so
Mass=No. of moles *molecular weight of CO2
Molecular weight of CO2=(1*12+2*16). As atomic mass of carbon and oxygen are 12&16respectively
12+32=44
Mass=1/6.022*10^23 *44
Mass =7.3065*10^23gm
I haven't done calculations myself, I have use the calculator
So you can use
At last, mass of one molecule of CO2 is 7.3065*10^23gm.
