The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg Β· s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Awelder using a tank of volume 7.50Γ10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30Γ10^5 pa and temperature of 37.1 βc. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 βc, the gauge pressure of the oxygen in the tank is 2.00Γ10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
