8.3 The Ideal Gas Law-Unit 8 States of Matter
The gas constant defines...
the units for the 4 variables in the equation
what are the different values of R?
0.08206 L atm/K mol 62.36 L mmHg/Kmol 8.31 L kPa/Kmol
Example: How many molecules of chlorine gas are in a 6.0 L ballon if it exerts a pressure of 29.6 kPa at 12°C?
4.5∙10²² molecules
The ideal gas law applies to...
MOST sample of gas. If a gas is at very HIGH pressure or a very LOW temperature, the gas will not follow ideal behavior.
Example: A sample of 0.443 g helium gas is in a 2.50 L tank with a pressure of 825 mmHg. At what temperature is the gas?
T=298k
Example: Calculate the volume of a sample of gas containing 1.00 mole of a gas at 273 K and a pressure of 1.00 atm.
V=22.4L
The Ideal gas...
is only law that includes all four variables that affect gas behavior using one equation: PV=nRT -R is known as the gas content. It has three different values.
