Answer to Question #74190 in General Chemistry for Asma
Question #74190
1.86 cm3 of a liquid of density 0.803 g cm-3was injected into a syringe maintained at 200°C.
The liquid vapourised completely and occupied 808.54 cm3 at 1.20 atm.
a) Calculate the volume that this sample of vapour will occupy at STP
b) Hence calculate the molar mass of the liquid
The liquid vapourised completely and occupied 808.54 cm3 at 1.20 atm.
a) Calculate the volume that this sample of vapour will occupy at STP
b) Hence calculate the molar mass of the liquid
Expert's answer
a) M=1.86*0.803=1.49358 g
V(STP)=(273/473)*(1.2/1.0)*808.54=560.0 cm-3
N=V/Vm=560/22400=0.025 mol
b) M=m/n=1.49358:0.025=59.7
V(STP)=(273/473)*(1.2/1.0)*808.54=560.0 cm-3
N=V/Vm=560/22400=0.025 mol
b) M=m/n=1.49358:0.025=59.7
