 The molar mass of a volatile substance was determined by the Dumas-bulb method described in Exercise 10.53. The unknown vapor had a mass of 0.846 g; the volume of the bulb was 354 cm3, pressure 752 torr, and temperature 100 °C. Calculate the molar mass of the unknown vapor. 


Expert Answer

Step 1


Mass of the gas = 0.846 g

Pressure 752 torr,

Volume = 354 cm3 = 0.354 L
