Answer:
n = m/M
Step-by-step explanation:
From the question, we're told that we have the following parameters constant, i.e, they don't change
Volume of V
Pressure of P
Temperature of T
Also, we're told that the gases in comparison have the same number of molecules,
Although they have different masses, which is only logical since they're all different gases.
We're asked to find the number of moles of gas in each vessel.
Finding the number of moles is represented by the formula,
n = m / M, where
n = number of moles we're interested in
m = mass of the gas, that we're told differs from each gas
M = molar mass of the gases that is unique to each and every gas.
That is how you find the number of moles of the gases in the vessel
