Question

Calculate how many moles there are in the following amount:

84.32 g of the diatomic molecule of Iodine

Answer 1

To find the number of moles of diatomic iodine in 84.32 g, divide the mass by the molar mass of I2 (253.8 g/mol), resulting in 0.3321 moles.

Step-by-step explanation:

To calculate the number of moles of diatomic iodine (I2) in 84.32 g, you first need the molar mass of I2. Iodine has a molar mass of approximately 126.90 g/mol, so I2 has a molar mass of 253.8 g/mol (126.90 g/mol × 2). Then, use the formula:

moles = mass of substance (g) / molar mass (g/mol)

Insert the given values:

moles of I2 = 84.32 g / 253.8 g/mol

The calculation then yields:

moles of I2 = 0.3321 mol

Therefore, there are 0.3321 moles of diatomic iodine in 84.32 g of I2.
