To calculate the number of moles of air in the given volume, we need to use the ideal gas law equation:

PV = nRT

Where:

P = pressure (in atmospheres)

V = volume (in liters)

n = number of moles

R = ideal gas constant (0.0821 L·atm/(mol·K))

T = temperature (in Kelvin)

First, let's convert the given dimensions from meters to liters:

Volume = 10 m × 10 m × 60 m = 6000 m³ = 6000000 liters

Next, we convert the temperature from 0°C to Kelvin:

T = 0°C + 273.15 = 273.15 K

Assuming the pressure is at one atmosphere (1 atm), we can substitute the values into the equation and solve for n:

1 atm × 6000000 L = n × 0.0821 L·atm/(mol·K) × 273.15 K

6000000 = 22.41415n

n = 6000000 / 22.41415

n ≈ 267987.12 moles

Therefore, approximately 267987.12 moles of air fill the given volume at one atmosphere and 0°C.
