OWL wrong or just me? Check out this problem?

Question

anonymous · Answer

$$(\frac{3RT(F2)}{Mm(F2)})^{1/2}=(\frac{3RT(Cl2)}{Mm(Cl2)})^{1/2}$$

anonymous · Answer

T=26.2 C = 299.2K
Mm=molar mass   (compounds are Fluorine gas F 2 and Chlorine Gas (Cl2)

anonymous · Answer

I can give the molar mass but this is basically a math problem

anonymous · Answer

squaring it and solving for T(Cl2) i get

$$T(Cl2)=\frac{T(F2)*Mm(Cl2)}{Mm(F2)}$$

anonymous · Answer

molar mass of fluorine gas is 37.9968064

molar mass of Cl2 gas = 70.906

anonymous · Answer

i got in celsius 285.3383766

anonymous · Answer

says it's wrong though?

anonymous · Answer

so i might send a displeased email to my teacher explaining how the problem would not take the right answer

anonymous · Answer

zarkon you there?

zarkon · Answer

I'm not familiar with the formulas given ...but using your formulas and your numbers I get  285.188376564

anonymous · Answer

you converted back to celsius right?

zarkon · Answer

yes

zarkon · Answer

got 558.33837656419 k

zarkon · Answer

are you supposed to use kelvin in the formula?

zarkon · Answer

when i convert 26.2C I get 299.35K

zarkon · Answer

using this number I get 285.468292194

zarkon · Answer

C

zarkon · Answer

does this formula have a name?

anonymous · Answer

yeah, i found out what it is.... so basically OWL likes to switch K to equal from 273 to 273.15.... so that 15 throws my answer off by one whole number and marks it wrong... i'm going to have a conversation with my teacher. I've had so many problems with Cengage's OWL quizes to the point where i feel like i might throw my computer out a window or something

anonymous · Answer

root-mean-square molecular speed

zarkon · Answer

sorry to hear that

anonymous · Answer

yeah well my teacher should know that she should give out different types of quizzes other than online quizzes. I mean how am i supposed to know whether the program is using 273 for the equation or 273.15

zarkon · Answer

it should definitely inform you if it is doing something like that.

anonymous · Answer

nope, it does it all the time also however usually it doesn't effect the answer as much as it does in thisquestion

anonymous · Answer

since the molecular masses are quite large

zarkon · Answer

ic

zarkon · Answer

at least you know what you are doing...that's good

anonymous · Answer

yeah i guess lol got calc 3 test and a chem test this week coming up
