Question

a flask of volume 1*10^ -3 contains3 0*10^12 oxygen molecules at
a certain temperature the mass of one molecule of oxygen is 5
3*10^-26 kg and root mean square velocity of its molecule at same
temperature is400 ms^-1 calculate the pressure of the oxygen gas in
the flask

Number of molecules per unit volume, n=3×10121×10-3=3×1015 Mass of one molecule of oxygen,m=5
3×10-26kgRoot mean square velocity,C=400 m/sUsing the expression for pressure,P=13mnC2=13×5
3×10-26×3×1015×4002=8 48×10-10Pa

a flask of volume 1*10^ -3 contains3.0*10^12 oxygen molecules at a certain temperature.the mass of one molecule of oxygen is 5.3*10^-26 kg and root mean square velocity of its molecule at same temperature is400 ms^-1.calculate the pressure of the oxygen gas in the flask.
