Question

30g of potassium iodide is present in 200g of its aqueous solution. Find mass percentage

Answer 1

Answer:

15%

Explanation:

the total mass of the aqueous solution is 200g

the mass of potassium iodide in this solution is 30g

so the mass percentage is 30*100/200

=15%.

Answer 2

Hope this helps you ;)

Total mass of solution = 200 g

Mass of Iodine = 30 g

$w\% = \frac{30}{200} \times 100$

$w\% = 15\%$
