Inside an industrial unit, the hourly average concentration of NO2 is measured at 0.12 ppm (by volume). Assume (i) 1 mol of an ideal gas at 1 atm and 25°C occupies 24.46 L of volume and, (ii) the molecular weights of Nitrogen (N₂) and Oxygen (O₂) are 28 and 32 respectively. From the data, the estimated concentration (in ug/m³, rounded off to two decimal places) of NO₂ at 25°C and 1 atm pressure is
