C. Also just look up a chemical equation balancer calculator next time.
A heterogeneous mixture is a mixture in which its components retain their identity. The correct answer is B.
Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
Now,
The molarity of the solution will be:
= 
On substituting the values, we get
= 
=
