How Much Of A 0250M Sucrose Solution Must Be Used To Prepare 4000mL Of A 00310M Solution class=

Sagot :

1) Preparing a dilution

[tex]C1\cdot V1=C2\cdot V2_{}[/tex]

C1: Initial concentration.

V1: Initial volume.

C2: final concentration.

V2: final volume.

2) List known values

C1: 0.250 M sucrose

V1:

C2: 0.0310 M sucrose

V2: 400.0 mL

3) Plug in known values and solve for V2

[tex]0.250\text{ M}\cdot V1=0.0310M\cdot400.0mL[/tex][tex]V1=\frac{0.0310M\cdot400.0mL}{0.250M}=49.6mL[/tex]

The solution should be made as follows

Add 49.6mL of 0.250M sucrose to 350.4mL of water to get 400.0mL of 0.0310 M sucrose.
