Question

define ideal gas equation

Answer 1

The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations

Answer 2

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
The terms are: p = pressure, in pascals (Pa).
R = the gas constant, 8.31 J K-1 mol-1 (you will be given this value).
