What is the concentration of a 1:15 dilution of a 3.0 M solution of nacl

0.20M NaCl is the concentration of the NaCl dilution

Explanation:

A dilution consist on the addition of more solvent in a solution in order to decrease their concentration.

In this problem, the 3.0M NaCl solution is decreasing their concentration 15 times. That is:

3.0M NaCl / 15 =

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
