Determine the concentration of a 1.00 M solution of sodium chloride (NaCl) after the following changes occur. (a) Exactly one liter of the solution is mixed with 0.40 L of water.

0.714 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the neutralization law,

where,

= molarity of stock  solution = 1.00 M

= volume of stock  solution = 1.00 L

= molarity of dilute  solution = ?

= volume of dilute  solution = (1.00+0.40) L = 1.40 L

The concentration of a 1.00 M solution of sodium chloride (NaCl) after exactly one liter of the solution is mixed with 0.40 L of water is 0.714 M
