5.00 ml is withdrawn from a 1.00l solution of nacl and diluted to 100.00 ml. if the concentration of the nacl in the 100.00 ml solution is 0.076, what is the concentration of nacl in the original 1.00 l solution? answers

The concentration of NaCl in 1.00 L of solution is 0.0076 M.

Explanation:

To calculate the molarity of the concentrated solution, we use the equation:

where,

are the molarity and volume of the concentrated solution

are the molarity and volume of diluted solution

We are given:

Conversion factor used: 1L = 1000 mL

Putting values in above equation, we get:

Hence, the concentration of NaCl in 1.00 L of solution is 0.0076 M.
