One method of removing CO2(g) from a spacecraft is to allow therm CO2 to react with LiOH. 2 LiOH(s) + CO2(g)->Li2CO3(s) +H2O(l) How many liters of CO2(g) at 24.7 degC and 753 Torr can be removed per 5 kg of LiOH consumed?

OpenStudy (anonymous):

alright Start with factor label going from lioh to co2 then plug that number into your ideal gas law.

OpenStudy (anonymous):

have tried but couldnt get it,dont know if the problem is from conversions

OpenStudy (anonymous):

well give me to molar mass for co2 and lioh and i will try.

OpenStudy (anonymous):

CO2 IS 44.011G/MOL

OpenStudy (anonymous):

LiOh->23.948

OpenStudy (anonymous):

$5000 g LIoh (\frac{1 mole LiOH}{23.948})(\frac{1 mole CO_2}{2 mole LiOH})=104.4 moles CO_2$ Now plug in 104.4 moles of CO2 into the equation PV=nRT

Solve for V

thanks,my mastering chemistry just accepted the answer...thanks alot :)

OpenStudy (anonymous):

whats my mastering chemistry?

OpenStudy (anonymous):

an online assignment...i have one question remaining to finish up,dont know if u can help me as well

OpenStudy (anonymous):

I can try

OpenStudy (anonymous):

I'll be back in a few min and take a look at it for you

OpenStudy (anonymous):

The u_rms of H2 molecules at 273K is 1.84*10^3 m/s At what temperature is u_rms for H2 1.9 times greater than this value?

OpenStudy (anonymous):

Sorry i have never heard of the term U_rms

OpenStudy (anonymous):

ok no problem...thanks for your help and consign

OpenStudy (anonymous):

it means root mean square

OpenStudy (anonymous):

dont understand what the did
