Answer:
The number of mole = 0.079 mole.
Explanation:
According to ideal gas equation,
PV = nRT.................... equation 1
Where P = pressure of the air, V = volume of the air, n = number of moles, R = molar gas constant, T = Temperature in (Kelvin), R = molar gas constant
Making n the subject of equation 1
n = PV/RT................... equation 2.
Where P = 101325 pa = 1 atm
V = 2.00 L = 2.00 dm³
T = 37 = 37 + 273 = 310 K, R= 0.082 atm/(dm³Kmol)
Applying these values in equation 1,
n = (2×1)/(310×0.082)
n = 2/25.42
n = 0.079 mole
Therefore the number of mole = 0.079 mole.
