For gases under certain conditions, there is a relationship between the pressure of the gas, its volume, and its temperature as given by what is commonly called the ideal gas law.The ideal gas law isPV = mRTwhereP = absolute pressure of the gas (Pa)V = volume of the gas (m3)m = mass (kg)R = gas constantT = absolute temperature (kelvin )What are the appropriate units for R if the preceding equation is to be homogeneous in units?
