An average adult has a total lung capacity of 6.0 l. how many total grams of air could be held in the lungs at a pressure of 102 kpa and a normal body temperature of 37° celsius? (assume that the average molar mass of air is 29 g/mol.)

The amount of air that could be held in lungs is 6.873g

Explanation:

To calculate the amount of air, we use the equation given by Ideal gas equation, which follows:

where,

P = Pressure of the gas = 102 kPa

V = volume of the gas = 6 L

n = number of moles of gas = ? mol

R = Gas constant =

T = temperature of the gas = 37°C = 310 K  (Conversion factor:

Putting values in above equation, we get:

To calcultae the mass of the air, we use the equation:

We are given:

Moles of air entered = 0.237 mol

Molar mass of air = 29 g/mol

Putting values in above equation, we get:

Hence, the amount of air that could be held in lungs is 6.873g
