Question

there is a proportinal 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

plz help

Answer 1

The constant of proportionality in this relationship is 5.6.

Proportional relationship:

Proportional relationship is a relationship between two variables where there ratios are equivalent.

The variables are as follows:

v = the volume of a sample of helium in litters

m = the mass of that sample in grams

Therefore,

v = km

where

k = constant of proportionality

Therefore,

k = 28 / 5

k = 5.6
