step 1 This problem gives us the amount of oxygen in grams and it's asking for the amount in moles. So

The average oxygen content of arterial blood is...

The average oxygen content of arterial blood is approximately 0.25 $\mathrm{g}$ of $\mathrm{O}_{2}$ per liter. Assuming a body temperature of $37^{\circ} \mathrm{C},$ how many moles of oxygen are transported by each liter of arterial blood? How many milliters?

Key Concepts

Mole Concept and Molar Mass

This concept involves converting a given mass of a substance to the number of moles, using its molar mass. For oxygen gas (O?), the molar mass is essential because it provides the conversion factor that links grams to moles, allowing one to quantitatively assess the amount of oxygen present in a sample.

Ideal Gas Law

The ideal gas law (PV = nRT) is used to relate the number of moles of a gas to its volume under specified conditions of temperature and pressure. This principle is crucial when converting the quantity of oxygen from moles to its corresponding volume, especially when conditions deviate from standard temperature and pressure.

Temperature Conversion

When applying the ideal gas law, it is necessary to convert the temperature from degrees Celsius to Kelvin. This conversion ensures that the calculations adhere to the absolute temperature scale required in gas law equations, enabling accurate determination of the gas volume under the given conditions.
