The graph above shows the distribution of molecular speeds for four different gases at the same temperature. What property of the different gases can be correctly ranked using information from the graph, and why? (Graph attached) I WILL MARK BRAINLIEST

A.) The densities of the gases, because as the density of a gas increases, the average speed of its molecules decreases.

B.) The pressures of the gases, because the pressure exerted by a gas depends on the average speed with which its molecules are moving.

C.) The volumes of the gases, because at a fixed temperature the volume of a gas can be calculated using the equation PV=nRT.

D.) The molecular masses of the gases, because the gas molecules have the same average kinetic energy and mass can be calculated using the equation KEavg=12mv2

The correct option is;

D.) The molecular masses of the gases, because the gas molecules have the same average kinetic energy and mass can be calculated using the equation,

Explanation:

The graph shows the proportion of the atoms of each gas have a given velocity

The given parameters of the graphs are;

The dependent variable of the graph = The number of molecules

The independent variable =  The molecular speed (m/s)

The temperature of the gases = The same temperature

Therefore, from the above equation, at constant temperature, the root mean square velocity varies inversely as the molecular weight

Similarly from the kinetic energy equation, we have;

Whereby, the energy contained in each of the four gas are the same, we have;

For increasing molecular mass by a factor of 2, the velocity decreases by a factor of 4.

girl imma just put my comment here because i need a couple point okurrttt
