A sample of carbon dioxide gas contains #6*10^22# molecules. How many moles of carbon dioxide does this represent?

Answer 1

The answer is #"0.1000 mol CO"_2"#.

#"1 mol CO"_2=6.022xx10^(23) "molecules CO"_2"#

Use the equality above to determine the moles of carbon dioxide as shown below.

#6.022xx10^22 cancel"molecules CO"_2xx(1 "mol CO"_2)/(6.022xx10^23 cancel"molecules CO"_2)="0.1000 mol CO"_2"# rounded to four significant figures

To determine the number of moles of carbon dioxide, you can use Avogadro's constant, which states that one mole of any substance contains approximately 6.022 × 10^23 molecules. Given that the sample contains 6 × 10^22 molecules, you can calculate the number of moles by dividing the number of molecules by Avogadro's constant:

Number of moles = Number of molecules / Avogadro's constant

Number of moles = (6 × 10^22 molecules) / (6.022 × 10^23 molecules/mol)

Calculate the result to find the number of moles of carbon dioxide in the sample.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
