An empty fuel unit is ejected from a spacecraft in deep space. There is no air or other gases here, and effectively no gravity. 1.) Describe how the fuel unit will move after being ejected.
2.) Explain why in terms of the first law of motion
(Please make it a paragraph.)

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
