Explanation: if see you have to times it and show it with times
Answer:
2.00 M
Explanation:
The concentration of a solution is given by

where
m is the mass of solute
V is the volume of the solution
At the beginning, the solution has:
M = 6.00 M is the concentration
V = 100 mL = 0.1 L is the volume
So the mass of solute (HCl) is

Then, the HCL is diluted into a solution with volume of
V = 300 mL = 0.3 L
Therefore, the final concentration is:

The term "product" refers to the result of one or more multiplications. For example, the mathematical statement would be read " times equals ," where.
