Explanation Given: Volume of liquid nitrogen, V = 1 .0 L Volume of the closet = 1.0 m × 1.0 m × 2.0 m Temperature, T = 25 ° C Pressure, P = 1.0 atm Density of liquid nitrogen, d = 0 .807 g/mL Explanation: V o l u m e o f t h e c l o s e t = 1.0 m × 1.0 m × 2.0 m = 2.0 m 3 As density is given in g/mL , the volume of the closet is converted into mL . 1 m 3 = 1000 L ∴ 2 .0 m 3 = 1000 L × 2 .0 m 3 1 m 3 = 2000 L Thus, the volume of the closet is 2000 L . As the closet is filled with air and liquid nitrogen, the volume of the closet is equal to the volume of the air and volume of nitrogen. However, the volume of nitrogen is 1.0 L ; therefore, the volume of air present in the closet is 1999 L . In order to determine the amount of gaseous nitrogen that would be formed when the liquid nitrogen evaporates, the mass should be determined. The mass of liquid nitrogen can be determined from its given density. Therefore, Mass of nitrogen = Density of liquid nitrogen × Volume of liquid nitrogen To find out the mass of liquid nitrogen, convert the density into g/L as follows: Density in g/L = 0 .807 g mL × 1000 mL L [ ∵ 1 L = 1000 mL ] = 807 g/L Substitute density of liquid nitrogen = 807 g/L and volume of the liquid nitrogen = 1.0 L in the above expression to get Mass of liquid nitrogen = 807 g L × 1.0 L = 807 g Molar mass of liquid nitrogen = 2 × 14 = 28 g / m o l Number of moles ( n ) = Mass of N 2 Molar mass of N 2 = 807 g 28 g /mol = 28

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…

Gaseous State

It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed fo…
