🔍 Key Concepts

• parts per million (ppm) as a ratio (part ÷ whole) × 1,000,000 • converting ounces to pounds so both quantities are in the same unit • setting up a fraction for concentration: mass of solute / mass of solution

💭 Think About

• First, how can you convert the 8 ounces of oxygen into pounds so that both masses (oxygen and water) use the same units? • Once both are in pounds, what fraction do you get when you divide the mass of oxygen by the mass of water? • How do you turn that fraction into ppm? (Think: multiply the ratio by 1,000,000.)

✅ Before You Answer

• Be sure you use the correct conversion: 16 ounces = 1 pound. • Confirm that your concentration is a dimensionless ratio before multiplying by 1,000,000 to get ppm. • After computing ppm, check if your final value is reasonable and small, since oxygen is a tiny fraction of the total mass.
