Question

A sample of carbon dioxide gas (CO2) contains 8.551 x 10^25 molecules. How many moles of carbon dioxide does this represent

Answer 1

Answer:

142.0mol CO2

Explanation:

To convert from molecules to moles we must divide the amount of molecules by Avagadro’s number, 6.02 x 10^23.

8.551 x 10^25 / 6.02 x 10^23 = 142.0mol CO2

Answer 2

Answer:

Explanation:

moles= no. of molecules/ avagardo number

        =8.511*10^25/ 6.022*10^23

        =14.13 moles
