To calculate the amount of mercury in µg (micrograms), we need to use the following formula:
mass (in µg) = volume (in mL) x concentration (in ppm) x atomic mass (in g/mol) / 1000
The atomic mass of mercury (Hg) is 200.59 g/mol.
Substituting the given values into the formula, we get:
mass = 27.2 mL x 14.10 ppm x 200.59 g/mol / 1000
mass = 76.9 µg
Therefore, there are 76.9 µg of mercury in 27.2 mL of a 14.10 ppm solution.
