Question

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. what is the constant of proportionality in this relationship,

in this situation, what is the meaning of the number you found in question 1?(explain in the short answer) Add at least three more points to the graph above, and label with their coordinates.(Show your work)

Answer 2

• v = 5.6m

Explanation:

Proportional relationship equation:

• y = kx, where k- constant of proportionality

Use the given point to work out the value of k:

• 28 = 5k
• k = 28/5
• k = 5.6

In our case the equation is:

• v = 5.6m, where v- volume, m- mass
