What is the concentration of nacl in solution made by mixing 25.0 ml of .100 m nacl with 75.0 ml of .175 m nacl

0.15625M

Explanation:

When you mix two liquids of the same solute and solvent but with different concentration and amounts then the resulting solutions molarity is given by

C.

in the above case given,

c1=0.1M

v1=25mL

c2=0.175M

v2=75mL

total volume=v1+v2=25+75=100mL.

so substituting thse values in the above equation gives C_{equivalent}[/tex]=15.625\100=0.15625M

it's c. elements are placed in rows based on how may valencies electrons have.
