Question

SOMEONE PLZ HELP ME..BIG TEST!!!
At 27C and 750 torr, both a 16 g sample of methane gas and 16 g sample of oxygen gas will have the same:
A. average molecular velocities
B. average molecular kinetic energies
C. number of gaseous particles
D. total gaseous volumes
E. average effusion rates

Answer 1

C, D and E are related to moles, so they must be wrong

Answer 2

it says b is the answer

Answer 3

but i want to know why

Answer 4

can u explain a little bit plz

Answer 5

Average molecular kinetic energy is related to the temperature

Answer 6

Actually average molecular kinetic energy IS temperature

Answer 7

yeah tht is right...

Answer 8

but they have the same pressure as well

Answer 9

why is tht

Answer 10

Since they have the same pressure

Answer 11

The bag containing the methane gas will be smaller in size

Answer 12

so thts why it couldnt be same gas particles or same volume.. right

Answer 13

Yep

Answer 14

and effusion rate is far too wild of an answer right

Answer 15

effusion rate has nothing to do with it, huh?

Answer 16

Effusion rate is proportional to the number of moles

Answer 17

I mean the square root of the ratio

Answer 18

https://en.wikipedia.org/wiki/Effusion

Answer 19

\[\frac{Rate_1}{Rate_2}=\sqrt{\frac{M_1}{M_2}}\]

Answer 20

oh ok thx

Answer 21

no problem

Answer 22

would u mind helping on a few more problems just a few

Answer 23

had to pull an all nighter...lol u noe how tht is
