The moles of the gas when a cylinder contains 30.0 l of oxygen gas at a pressure of 1.9 atm and a temperature of 310 K is 2.2
The ideal gas equation is PV=nRT. P is the pressure, V is the volume, n is the number of moles and T is the temperature
Substituting the values, we get
1.9x30=nx0.0821x310
n=2.2(two significant figures)
- An ideal gas is one that follows the ideal gas equation.
- It is also called the equation of state of a hypothetical ideal gas.
- It is an extension and generalization of Boyle's and Charles's law.
