There is a proportional relationship between the volume of a sample of helium in liters and the mass of that sample in grams. If the mass of a sample is 5 grams, its volume is 28 liters. (5, 28) is shown on the graph below. a. What is the constant of proportionality in this relationship?
b. In this situation, what is the meaning of the number you found in part a?
c. Add at least three more points to the graph above, and label with their
coordinates.
d. Write an equation that shows the relationship between the mass of a sample of
helium and its volume. Use for mass and for volume.
