ANSWER
EXPLANATION
Given that
The number o molecules is 6.02 x 10^23 molecules
Firstly, find the number of moles using the below formula
[tex]\text{ mole = }\frac{\text{ number of molecules}}{\text{ Avogadro's number}}[/tex]Recall, that the Avogadro's number is 6.02 x 10^23
[tex]\begin{gathered} \text{ mole = }\frac{6.02\text{ }\times\text{ 10}^{22}}{6.02\text{ }\times\text{ 10}^{23}} \\ \text{ mole = 1} \end{gathered}[/tex]Secondly, find the mass of CO2 using the formula below
[tex]\text{ mole = }\frac{mass}{\text{ molar mass}}[/tex]Recall, that the molar mass of CO2 is given as 44.01 g/mol
[tex]\begin{gathered} \text{ mole = }\frac{\text{ mass}}{\text{ molar mass}} \\ \text{ mass = mole }\times\text{ molar mass} \\ \text{ mass = 1 }\times\text{ 44.01} \\ \text{ mass = 44.01 grams} \end{gathered}[/tex]Therefore, the mass of CO2 is 44 grams
