How many moles are in 7.39 x 1023 molecules of ICl?
7.39*10^23 / 6.02*10^23 = 7.39/6.02 = ____ moles
To determine the number of moles in a given amount of molecules, you need to use Avogadro's number. Avogadro's number is defined as 6.022 x 10^23, and it represents the number of atoms or molecules in one mole of a substance.
To find the number of moles in 7.39 x 10^23 molecules of ICl, you can follow these steps:
1. Determine the number of molecules in one mole of ICl by using Avogadro's number:
1 mole = 6.022 x 10^23 molecules
2. Set up a conversion factor to convert from molecules to moles:
7.39 x 10^23 molecules / (6.022 x 10^23 molecules/mole)
3. Divide the number of molecules by the conversion factor:
(7.39 x 10^23 molecules) / (6.022 x 10^23 molecules/mole)
4. Perform the calculation to find the number of moles:
= 1.227 moles (rounded to three decimal places)
Therefore, there are approximately 1.227 moles in 7.39 x 10^23 molecules of ICl.
To find the number of moles in 7.39 x 10^23 molecules of ICl, we need to use Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 molecules.
So, the number of moles is calculated by dividing the number of molecules by Avogadro's number.
Number of moles = Number of molecules / Avogadro's number
= 7.39 x 10^23 / 6.022 x 10^23
To simplify this division, we can divide both the numerator and denominator by 10^23:
Number of moles = (7.39 / 6.022) x (10^23 / 10^23)
≈ 1.226 moles
Therefore, there are approximately 1.226 moles in 7.39 x 10^23 molecules of ICl.
