Answer :
1) List the known quantities
Initial conditions
Concentration 1: 1.6 M
Volume 1: 175 mL
Final conditions
Volume 2: 1 L
Concentration 2: unknown
2) Set the equation
[tex]C1*V1=C2*V2[/tex]3) Convert units
Volume
1 L = 1000 mL
[tex]mL=1\text{ }L*\frac{1000\text{ }mL}{1\text{ }L}=1000\text{ }mL[/tex]4) Plug in the known quantities and solve for C2
[tex](1.6\text{ }M)*(175\text{ }mL)=C2*(1000\text{ }mL)[/tex][tex]C2=\frac{(1.6\text{ }M)*(175\text{ }mL)}{(1000\text{ }mL)}[/tex][tex]C2=0.28\text{ }M[/tex]
The new concentration is 0.28 M.
