I'm answering questions for an Ideal Gas Law Lab. Help?

Question

gebooors · Answer

Maybe I could help?
What is the problem?

anonymous · Answer

If some of the bubbles of butane did not enter the flask and escaped into the air instead, in what way would the calculated molecular weight of butane be affected? This one I tried to answer: The molecular weight would be higher.

gebooors · Answer

pV = nRT, and n = m/M,  did you solve M = mRT/pV?

anonymous · Answer

Yeah, I'm not sure that we're answering them with numbers. And I don't know how to compare the problem with the question. But i'll give you the numbers I have

gebooors · Answer

If you think Volume is smaller because part of butane gas
Escaped, you get higher molar mass, also you was right.

Okay good. The other one I don't have an answer for: If the temperature measurement of the water was too high, in what way would the calculated molecular weight of butane be affected?

gebooors · Answer

Again examine the same formula. How it affect to result
Is real temperature is lower? Is the result M too high or
Too low?

anonymous · Answer

I guess logically it'd be higher. I had a feeling it would be but didn't want to just go on chance.

gebooors · Answer

You have right logic :)
If you try numbers, you can be sure

anonymous · Answer

Yeah I did. I changed the temperature to 318K instead of 295K

Can you help me with one more?
