To determine the number of moles containing a given number of molecules, we need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.
Given:
Molar mass of the compound = 90 g/mole
Number of molecules = 3.011 x 10^3 molecules
To find the number of moles, we can use the equation:
Number of moles = Number of molecules / Avogadro's number
Number of moles = 3.011 x 10^3 molecules / (6.022 x 10^23 molecules/mole)
Number of moles ≈ 4.998 x 10^-21 moles
Therefore, the number of moles containing 3.011 x 10^3 molecules in a compound with a molar mass of 90 g/mole is approximately 4.998 x 10^-21 moles.
