The molar mass of unknown gas is 63.5 g/mol
calculation
let the unknown gas be represent by letter Y
The rate of effusion of a gas varies inversely with square root of molar mass
that is R(CH4)/ R(Y)= √[(M(Y)/M(CH4)]
= 47.8 ml/min/24.0ml/min= √[(Y/16g/mol)]
square both side to remove square root sign
=47.8²ml/min /24²ml/min= Y/16 g/mol
=2284.84ml/min/576ml/min=Y/16g/mol
multiply both side by 16
y =63.5 g/mol
Answer:
hello :)
Explanation:
Water vapor in the air reaches its dew point as it cools in the air around the can, forming <em>liquid</em> <em>drops</em> <em>of</em> <em>water</em>. Condensation is the process where water vapor becomes liquid.

Explanation: your welcome
Answer:
Okay, I think I may actually have an answer for you. I would go with C, "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
Explanation:
I just took a quiz with a similar question, and B is the only gas particle that is able to react. This cancels out all the other answers, as A and B are obviously incorrect based on that information, and it rules out D because T1 is the only sample with a particle able to react. I hope this helps!
air that is cooling will cause the highest pressure
Explanation:
This is because heat has to escape a certain area and if the heat can't escape then more and more pressure will build up in a area.
