ch 1 stoichiometry

Question 1

how can the relative isotopic abundance be determined?

Answer 1

using mass spectrometry
ionizing atoms and allowing them to deflect according to their mass/charge ratio (m/z ratio)

Question 2

how should a graph of n (y-axis) against T (x-axis) look like, given the other variables in the equation PV = nRT are kept constant?

Answer 2

since they are inversely proportional to each other, the graph should look like a curved “L”, graph will not touch the axes.
