show how the value of the gas constant R in the ideal gas law equation can be determined by the vapor density method with gas of known molar mass.
{ Hint: set n = g/mm and then solve for R }
{ Hint: set n = g/mm and then solve for R }

PV=nRT n=mass/Molar Mass
P/RT=n/V=m/MM/V
P/m/MM/V=R
P/RT=n/V=m/MM/V
P/m/MM/V=R
