Question

1. Calculate the dilution factor and final concentration of the following target analytes:

20 mL of target analyte (2.5 M), to a final volume of 100 mL

2 mL of target analyte (3.23 ppm), to a final volume of 0.05 L.

5 mL of target analyte (15.9032 %), to a final volume of 1 dL.

1 dL of target analyte (4.0989 M), to a final volume of 0.25 L

0.025 L of target analyte (1.8982 g / L), to 79 g of ethanol.

10 mL of target analyte (2.0902 g / L), to 66.5 g of dichloromethane.
