Given number of moles to be 2.5mol, we can use it and the molar mass of glycerine which is 92.11g/mol to determine it's mass. That is,
m=nMr
m=2.50mol*92.11g/mol
m=230g
Density is s ratio of the mass and the volume, so we use this relationship to find the volume to obtain 2.5mol,C3H8O3
V=m/D
V=230g/1.26g/ml
V=183ml
