Answer 1

given that ,

mass of flask (m1) =72.22

mass of flash (m2) = 72.34

temperature of boiling water bath =100c

volume of flask =154ml

barometric pressure =754.1mmhg

room temperature =22.0 c

vapour pressure at room pressure = 100mmhg

Molarity =weight in gm X1000/molecular weight

=molarityXvolume in ml

=72.22X1000/72.34

=72.22/72.34X 154

=1.24X1000X154

=124000X154

=190.9600mmhg
