Question

Express the concentration of cotinine in this study in ppm, ppb, and molarity. Assume the density of the wastewater is \( 1.0 \mathrm{~g} / \mathrm{mL} \). \( (1000 \mathrm{~g} / \mathrm{L}) \). concentration: \( 1.43 \times 10^{-3} \) ppm concentration: 1.43 ppb concentration: \( \square \) M The wastewater treatment plant where these measurements were taken serves a community of 100,000 people and processes a volume of \( 83,000 \mathrm{~m}^{3} \) of wastewater per day. Based on this, what mass of cotinine enters the treatment plant each day? Report your answer in grams. mass of cotinine: \( \square \) g If \( 17 \% \) of the nicotine that humans consume is excreted as cotinine, estimate the total daily nicotine consumption for this community. mass of nicotine consumed daily: \( \square \) g If the nicotine dose in a single cigarete is \( 1.6 \mathrm{mg} \), estimate the number of doses consumed per day in this community.
