How is the mass defect determined? A. The mass defect is determined by measuring the mass of emitted
alpha particles
B. The loss of mass of a nucleus is determined by looking at its line
spectrum
C. The parent nuclear mass is divided by the daughter nuclear mass.
D. The mass of a nucleus is subtracted from the mass of its
components.

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.
