Question

When 7.50 grams of Iodine (I2) is added to 48.7 grams of Carbon Tetrachloride (CCl4), the iodine dissolves and a solution is formed. What is the weight percent of the iodine in the solution?

Answer 1

Answer:

weight percent of Iodine in the solution is 13.34%

Explanation:

Weight percentage -

weight percentage of A is given as , the weight of the substance A by weight of the total solution multiplied by 100.

i.e.

weight % A = weight of A / weight of solution * 100

From the question ,

weight of Iodine = 7.50 g

weight of carbon tetrachloride = 48.7 g

iodine is the solute and carbon tetrachloride is the solvent ,

Since,

solution = solute + solvent.

Hence,

weight of solution = weight of solute ( iodine ) + weight of solvent ( carbon tetrachloride)

weight of solution =  7.50 g + 48.7 g = 56.20 g

now,

weight of Iodine is calculated as,

weight % iodine = weight of iodine / weight of solution * 100

weight % iodine = 7.50 g / 56.20 g * 100

weight % iodine = 13.34 %
