To find the number of grams of CaI2, we need to use the molar mass of CaI2. The molar mass of CaI2 is 293.89 grams/mol.
To calculate the grams of CaI2 in 3.28 moles, we can use the formula:
grams = moles * molar mass
So, the calculation would be:
grams = 3.28 moles * 293.89 grams/mol
Let me do the math for you.
