Answer:
130 gram of NaN₃should be put into the compartment
Explanation:
Given that Ideal volume for an airbag = 50 lit
Pressure = 765 mmHg
we know
[tex]1 atm=760mmHg[/tex]
∴ [tex]765mmHg =\frac{765}{760}atm[/tex]
Temperature (T) = 29.5°C = (29.5 + 273) = 302.5 K
We know A/c to ideal gas equation
PV = nRT
[tex]n=\frac{PV}{RT}[/tex]
Where n= no. of mole
R = universal gas constant = 0.0821 lit. atm. mol⁻¹K⁻¹
[tex]n=\frac{\frac{765}{760} X50}{0.0821X302.5}=2 mole[/tex]
Mass of (NaN₃) = mole x molar mass = 2 x 65 = 130 gram
