## anonymous 4 years ago 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?

1. anonymous

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

2. anonymous

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

3. anonymous

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

4. anonymous

CO2 IS 44.011G/MOL

5. anonymous

LiOh->23.948

6. 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

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

11. anonymous

I can try

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?

14. anonymous

Sorry i have never heard of the term U_rms

15. anonymous

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

16. anonymous

it means root mean square
