A solution of I2was standardized with ascorbic acid. Using a 0.1000-g sample of pure ascorbic acid, 25.32 mL of I2 Are required to reach the starch end point. (a)What is the molarity of the iodine solution

0.02244 M is the molarity of the iodine solution.

Explanation:

Ascorbic acid + → dehydroascorbic acid +

Moles of ascorbic acid =

According to reaction, 1 mole of ascorbic acid reacts with 1 mole Then 0.0005682 mole of ascorbic caid will :

of solution

Moles of solution = 0.0005682 mol

Volume solution = 25.32 mL = 0.02532 L( 1 mL= 0.001 L)

Molarity of the solution :

0.02244 M is the molarity of the iodine solution.

d.) circle motion requires a force to give it a centripetal acceleration.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
