Respuesta :
The concentration of the solution in grams per mL is 0.0430 g/mL
From the question,
We are to determine the concentration in grams per mL of the solution.
First, we will determine the mass of iodine present in the solution
Using the formula
Mass = Number of moles × Molar mass
From the given information,
Number of moles of iodine = 0.0762 moles
and
Molar mass of iodine = 253.8089 g/mol
∴ Mass of iodine present = 0.0762 × 253.8089
Mass of iodine = 19.3402 g
Now, the concentration of the solution in grams per mL is
Concentration in grams per mL = [tex]\frac{Mass}{Volume}[/tex]
From the question,
Volume = 450.0 mL
∴ Concentration of the solution in grams per mL = [tex]\frac{19.3402}{450.0}[/tex]
Concentration of the solution in grams per mL = 0.0429782 g/mL
Concentration of the solution in grams per mL ≅ 0.0430 g/mL
Hence, the concentration of the solution in grams per mL is 0.0430 g/mL
