how many CaI2 are presented in 3.28 moles?
To determine the number of CaI2 molecules in 3.28 moles, we need to use Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 representative particles.
We start by calculating the number of molecules in 3.28 moles of CaI2:
Number of molecules = number of moles × Avogadro's number
= 3.28 moles × (6.022 x 10^23 molecules/mole)
Let's calculate this:
Number of molecules = 3.28 × (6.022 x 10^23)
≈ 1.97776 x 10^24 molecules
Therefore, there are approximately 1.97776 x 10^24 CaI2 molecules in 3.28 moles of CaI2.
