(b) Explanation Given The absolute temperature of the gas is 35 ° C . The absolute pressure of the gas is 685 torr . The mass of the gas is 2.50 g . The volume occupied by the gas is 0.875 L . The conversion of torr into atm is done as, 1 torr = 1 760 atm Hence, the conversion of 1.78 torr into atm is, 685 torr = 685 × 1 760 atm =0 .9013 atm The conversion of ° C into Kelvin is done as, T ° C = T + 273 K Hence, the conversion of 35 ° C into Kelvin is, 35 ° C = 35 + 273 K = 308 K The mass of a gas can be calculated by using ideal gas equation

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…
