How many moles are in a sample of 4.57 x 10^24 atoms of neon (ne)?

Hello!

To find the number of moles in a sample of 4.57 x 10^24 atoms, we need to use Avogadro's number, which is 1 mole = 6.02 x 10^23.

To find how many moles, we divide the given sample by Avogadro's number.

(4.57 x 10^24) / (6.02 x 10^23) ≈ 7.59136

Using the amount of significant figures given (3), the answer is 7.59 moles of neon (Ne).

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
