Question

Whitney's lung capacity was measured as 3.4 l at a body temperature of 37°C and a pressure of 743 mmhg. How many moles of oxygen are in her lungs if air contains 21

Answer 1

To calculate the number of moles of oxygen in someone's lungs, use the ideal gas law equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. Rearrange the n and plug in the given values to find the number of moles.

Step-by-step explanation:

The question asks about the number of moles of oxygen in someone's lungs, given the lung capacity, body temperature, and pressure. To find the number of moles, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. First, we need to convert the 273.15. Then, we can rearrange the equation to solve for n: n = PV/RT. Plug in the given values, convert the units if necessary, and calculate the number of moles.

the number of moles of oxygen in someone's lungs, use the ideal gas law equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. R is the gas constant, and T is the temperature in Kelvin. First, we need to convert the temperature from Celsius to Kelvin by adding 273.15 Rearrange the equation to solve for n and plug in the given values to find the number of moles.
