Question

Concerning the 10.0 mL of 0.50 M NaCl 100 mL of soltion:Does the dilution change the concentration

[]yes
[]no

Answer 1

yes................

Answer 2

The answer is affirmative because dilutions give you a weaker Molarity
Plase see this in the dilution formula that follows:

C1V1 = C2V2
(0.50M) (10.00ml) = (C2) (100ml)
C2 = 0.050 M
10X's weaker
Hope this helps a lot
