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?

I asked this question earlier but I think I forgot to include a conversion wht we know : mm of citrix acid = 192.14g/moldensity of citrix acid =166g/cm3 1 lime = 2tbsp of juice = 6 tsp 1tsp = 4.929x10-3L Q: assume citrix acid makes up 7.96% by volume of the lime juice . How many moles of citrix acid are in the recipe ( calls for 1 lime juice)
