Determine the volume of one part for each problem: need a total volume of 1 L using the following stock concentrations: Determine the volume of stock solution and the volume of diluent that should be used: -need a total volume of 1 L using the following stock concentrations: -need a total volume of 50 mL using the following stock concentrations: Now we are doing to mix up the information that you are given. You may not necessarily have C_1, C_2, and V_2 to start with in each of these problems. -How much final volume can you make if you use all 50 mL of a 5x concentrated stock?

Solution

E.

Stock = 20x

Required = 1x

Volume= 1L=1000 mL

C1V1= C2V2

(stock)   (required)

V1=C2V2/C1

V1 = (1x X 1000 mL)/ 20x

= 50 mL

50 mL of stock +950 mL of H2O

===========================

Stock = 10x

Required = 1x

Volume= 1L=1000 mL

C1V1= C2V2

(stock)   (required)

V1=C2V2/C1

V1 = (1x X 1000 mL)/ 10x

= 100 mL

100 mL of stock +900 mL of H2O
