What is the concentration of the nacl solution that results when 0.15 0 l of 0.556-m solution is allowed to evaporate until the volume is reduced to 0.105 l?

The concentration of evaporated solution is 0.794 M

Explanation:

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

where,

are the molarity and volume of the evaporated solution

are the molarity and volume of initial solution

We are given:

Putting values in above equation, we get:

Hence, the concentration of evaporated solution is 0.794 M

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
