Liquid nitrogen has a density of 0.808 g/mL and boils at 77 K. Researchers often purchase liquid nitrogen in insulated 151 L tanks. The liquid vaporizes quickly to gaseous nitrogen (which has a density of 1.15 g/mL at room temperature and atmospheric pressure) when the liquid is removed from the tank. Suppose that all 151L of liquid nitrogen in a tank accidentally vaporized in a lab that measured 12.00mX12.00mX3.00m.
Equation = Volume of gas/Volume of room
Imagine that you have a 5.00L gas tank and a 4.50L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
