We’re being asked to calculate for the molar mass at 97°C and 0.958 atm.
To calculate for the molar mass, we’re going to use the ideal gas equation.
A chemist vaporized a liquid compound to determine its molar mass. If the density of the vaporized liquid (collected in a 120 mL flask) at 97°C is 3.24 g/L, and the pressure exerted by the vaporized liquid is 0.958 atm, what is its molar mass?
(a) 103 g/mol
(b) 121 g/mol
(c) 187 g/mol
(d) 31.6 g/mol
(e) Insufficient information was given to calculate molar mass.
