Find the mass in grams of a carbon dioxide molecule.

Question

Physics 

Answer 1

There are several ways to answer this.  I think the easiest is to find the molecular weight of CO₂ in grams/mole, and divide by Avogadro's number (A₀), which is 6.02 x 10²³.  Look up the atomic weights (in grams/mole) of C and O, and add C+2(O).  That will be the mass in grams for 1 mole of CO₂.  Divide that by A₀ and you will have the mass in grams of a single CO₂ molecule.
