Answer to Question #287847 in General Chemistry for Jesse

Question

A certain concentration method works best when the analyte’s concentration is approximately 10 ppb.

a. If the sampling volume for the method is 0.5 mL, about what mass of analyte is being measured?

Answer 1

Given that, Concentration = 10ppb Volume = 0.5ml We have, ppb = (grams of analyte/volume in ml) ×10^9

10(0.5)( ×10^9)=50
