The Total solution for NCERT class 6-12
According to ideal gas equation,PV = n RT ; PV = M orM = PVAccordingto available data :Mass of phosphorus vapours (W) = 0.0625 gVolume of vapours (V) = 34.05 mL = 34.05 × 103 LPressure of vapours (P) = 1.0 bar.Gas constant (R) = 0.083 bar L K-1 mol-1Temperature (T) = 546 + 273 = 819 K
