Answer :
The study of chemicals and bonds is called chemistry.
The correct answer is B that is 42.8 grams of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 L
What is the procedure?
- The procedure is defined as the systematic action to perform an experiment.
The volume of water in 2kg of water might not be 2L
To solve the question, we need to know that the number of moles equals the mass over the molar mass. Doing this with the particular data in the tie question would give 0.2M.
Hence it is essential that what we get is 0.2M in one liter. But since we are gunning for 2L, adding more than one liter of water would affect the molarity, that is why it now will be 0.1M in 2L
Hence, we can conclude that the correct answer is option B.

Answer:
B
Explanation:
A. Wrong
The volume of water in 2kg of water might not be 2L
D is correct.
Firstly, we need to know that the number of moles equals the mass over the molar mass. Doing this with the particular data in tie question would give 0.2M.
Hence it is essential that what we get is 0.2M in one liter. But since we are gunning for 2L, adding more than one liter of water would affect the molarity, that is why it now will be 0.1M in 2L
C is wrong
What is prepared here is 0.05M in 2L
B is wrong
What is needed is actually 2L of water and not the total volume of both being 2L
E is wrong
