Since C-12 has a mass of 12.0 amu and occurs as 98.9 % abundant; the C-13 has a mass of 13.0amu and occurs as 1.O% abundant, and the C-14 has a mass of 14.0 amu and occurs as 0.1% abundant; Show a numerical set up for the determination of the atomic mass of carbon, then the resulting answer.

What is the mass of 4 molecules of co2

Kp is the equilibrium constant for dissociation of the propionic acid dimer. what is the sign of the slope for a plot of the natural logarithm of kp vs. inverse temperature for this reaction?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
