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
in per unit time some things velocity changes rate is called acceleration
