(a) Explanation Given The temperature of the air inside the cylinder is 74 ° C . The pressure exerted by air is 0.980 atm . The volume of the cylinder is 524 cm 3 ( = 524 mL ) . The mole fraction of oxygen is 0.2095 . The conversion of volume from mL into L is done as, 1 mL = 10 − 3 L Hence, the conversion of 524 mL into L is, 524 mL = 524 × 10 − 3 L = 0.524 L The conversion of temperature from ° C into Kelvin is done as, T ( ° K ) = T ( ° C ) +273 Where, T ° C is the temperature in degree Celsius. T ° K is the temperature in Kelvin. Hence, the conversion of temperature from 74 ° C into Kelvin is, T ° K = 74 + 273 = 347 K The number of moles of air present in the cylinder is calculated by using ideal gas equation. P V = n R T n = P V R T Where, n is the number of moles of the gas. P is the absolute pressure of the gas. V is the volume of the gas. T is the absolute temperature of the gas. R is the gas constant ( 0 (b) Interpretation Introduction To determine: The mass of C 8 H 18 used in its complete combustion.

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…
