State what is the ppm concentration

Reference no: EM13183398

A) Determine the concentration in molarity (M) of a crystal violet solution based on a measured absorbance of 0.652 at 590 nm at a path length of 1.0 cm .

B) Based on your determined concentration (in molarity,M), how many grams of crystal violet were dissolved in the 2 mL of water used to prepare the sample for the cuvette?

C) What is the ppm concentration? The molar extinction coefficienet is 87,000 M^-1cm^-1 and the molecular weight is 407.98 g/mol. The density of water is 1.00 g/mL.
