Q1) A student obtained the following set of data:
Mass of condensed liquid = 0.74 g
Volume of flask = 258 mL
Atmospheric pressure = 742 mm Hg
Temperature of boiling water = 97.2 °C
Calculate the molar mass of the liquid ( in g/mol),
R 0.08206 atm.L/mol/K, atm = 760 mmHg
Q2) The density of the vapor of a volatile liquid was found to be 1.20g/L at 147
°C and 450 mmHg. Calculate the molar mass of the volatile liquid in (g/mol).
