Hi, your question was incomplete, hence I am writing down the complete question below.
Q)The displacement x of a particle of rest mass m0, resulting from a constant force m0g along the x-axis, is
x= c2/g{[1+(gt/c)2]power0.5-1}
including relativistic effects. Find the displacement x as a power series in time t. Compare with the classical result.

n N2(g) = 15.367 mol
Explanation:
airbags generally vary between 35 and 60 liters in volume and for the airbag system to activate, it takes about 20 Kgf/cm² of pressure; with this data taken from literature and knowing the temperature of reaction (495 °C), we determine the moles of nitrogen needed from the ideal gas law.
ideal gas law:
PV = RTn∴ P = 20 Kgf/cm² * ( 0.9678 atm / Kgf/cm² ) = 19.356 atm
∴ V = 50 L average volume
∴ R = 0.082 atm * L / K * mol
∴ T = 495°C + 273 = 768 K
⇒ n = PV / RT
⇒ n = ((19.356 atm) * (50 L)) / ((0.082atm*L/K*mol) * (768K))
⇒ n = 15.367 mol N2(g)
