What is the molarity of a solution that contains 0.400 mol hcl in 9.79 l solution?

Explanation:

1) Data:

a) Molarity, M = ?

b) Number of moles, n = 0.400 mol

c) Volume, V = 9.79 liters

2) Formula:

The definition of molarity is number of moles of solute per volume of solution in liters.

3) Calculations:

You  must use three significant digits to report the answer correctly, so it is M = 0.0409 M.

dynamic equilibrium is the answer.
