Answer 2

mark me as brainliest answer

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.
