How many moles are in #4.65 times 10^24# molecules of #NO_2#?

Answer 1

Noah Aldrich

Well, one mole contains #6.022xx10^23# #NO_2# molecules....

Thus, we calculate the quotient.

#(4.65xx10^24*NO_2* "molecules")/(6.022xx10^23*NO_2* "molecules"*mol^-1)=7.72*mol#...

What is the molar quantity's mass?

To determine the number of moles in 4.65 × 10^24 molecules of NO2, we need to use Avogadro's number, which is approximately 6.022 × 10^23 molecules per mole.

Number of moles = Number of molecules / Avogadro's number Number of moles = 4.65 × 10^24 / 6.022 × 10^23 Number of moles ≈ 7.73 moles

Therefore, there are approximately 7.73 moles in 4.65 × 10^24 molecules of NO2.

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.
