Molecular weight of a volatile liquid A student had the following data: mass of volatile liquid: 0.317 g pressure: 1.076 atm temperature C: 97.8 volume of flask: 130.8 mL The student calculated the molar mass to be 0.06857 g / mol which is impossible since H has a molar mass of 1.008 g / mol! The error that the student made was ... A) Not converting Celsius to Kelvin B) No errors were made.   C) This unusual compound does have a fractional molar mass less than one and is the only known compound with such a mass. D) Not converting the volume from mL to L E) Using the wrong gas constant

Molecular weight of a volatile liquid

A student had the following data:
mass of volatile liquid: 0.317 g
pressure: 1.076 atm
temperature C: 97.8
volume of flask: 130.8 mL

The student calculated the molar mass to be 0.06857 g / mol which is impossible since H has a molar mass of 1.008 g / mol!

The error that the student made was ...

A) Not converting Celsius to Kelvin
B) No errors were made.  
C) This unusual compound does have a fractional molar mass less than one and is the only known compound with such a mass.
D) Not converting the volume from mL to L
E) Using the wrong gas constant
