A sample of CO2 contains 5.2 x1024molecules. How many moles of Carbon dioxide are in this sample?
Responses
8.6 moles
8.6 moles
0.1 moles
0.1 moles
3.1 x 1048 moles
3.1 x 10 48 moles
31.3 moles
To find the number of moles of carbon dioxide in the given sample, we can use Avogadro's number, which states that there are 6.022 x 10^23 molecules in one mole of a substance.
Given:
Number of molecules of CO2 = 5.2 x 10^24
Number of moles = Number of molecules / Avogadro's number
Number of moles = (5.2 x 10^24) / (6.022 x 10^23) = 8.63 moles
Therefore, the correct answer is 8.6 moles.
