What is the concentration of a dextrose solution prepared by diluting 11 mL of a 5.0 M dextrose solution to 25 mL using a 25 mL volumetric flask?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
