If 240 mL of water is added to 13 mL of 5.0 M NaCl solution,
zavuch27 [327]

Answer:

The correct answer is 0.26 M

Explanation:

The initial concentration of NaCl solution (Ci) is 5.0 M. The initial volume of the solution (Vi) is 13 mL. The final volume is the addition of 240 mL to 13 mL (Vf= 13 mL + 240 mL= 253 mL).

In order to calculate the final concentration of the solution (Cf) we can use the following expression:

Ci x Vi= Cf x Vf

This mathematical expression is often used to calculate concentrations in dilution procedures. So, we introduce Ci, Vi an Vf in the expression and we calculate Cf:

Cf= (Ci x Vi)/Vf= (5.0 M x 13 mL)/253 mL= 0.257 M ≅ 0.26 M

An adolescent client with an antisocial personality disorder has been admitted to the hospital because of drug abuse and repeate
Yuri [45]
The correct answer is "identifies the feelings underlying the acting-out behaviour ".
This statement shows that the adolescent is recognizing the feelings and is ready to talk about them. This willingness to express this indicates the development of insight and the sincere need to investigate the true source of these behaviours.
By stating that he will never behave like that again and that he will conform to society's norms, he is simply using expressions with no meaning to him. If he discusses seducing other adolescents, he is just manifesting the behaviour that led him to the hospital in the first place.
