In this lesson, we will learn how to calculate the concentrations of mixed or dissolved compounds in units of parts per million and parts per billion.
According to the US Environmental Protection Agency, when the concentration of lead in tap water reaches 15 ppb, certain remedial actions must be taken.
What is this concentration in ppm?
At this concentration, what mass of lead (μg) would be contained in a typical glass of water (300 mL), assuming a density of 1.0 g/mL?
