Question

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?

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

CO2 IS 44.011G/MOL

Answer 5

LiOh->23.948

Answer 6

\[5000 g LIoh (\frac{1 mole LiOH}{23.948})(\frac{1 mole CO_2}{2 mole LiOH})=104.4 moles CO_2\]

Now plug in 104.4 moles of CO2 into the equation

PV=nRT

Answer 7

Solve for V

Answer 8

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

Answer 9

whats my mastering chemistry?

Answer 10

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

Answer 11

I can try

Answer 12

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

Answer 13

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?

Answer 14

Sorry i have never heard of the term U_rms

Answer 15

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

Answer 16

it means root mean square
