Concept explainers

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…
Question

What is its new volume in Liters? 2. At what temperature in °C does 0.505 moles of gas occupy a volume of 8.15 Liters at a pressure of 0.750 atm? 3. a) How many moles of Cl2 gas occupy a volume of 695 mL at 6.40 atm and 337 Kelvin? b. How many grams of Cl2 gas are present? 4. A gas at constant pressure occupies a volume of 200.0 mL at 27.0°C . At what temperature in °C would the volume be 280.0mL ?
