Please help me answer this one chemistry question.

LiOH + CO2 → Li2CO3 + H2O

how many grams of Li2CO3 are produced from the complete reaction of 71.85 g of LiOH ?

First of all, I've only posted two questions. That one being my second. So why don't you shut up and go back to jerking your dad off.

Try using a site like this one because this isnt a homework help site. And clean up your attitude a bit if you ever expect help from anyone on here.

It's not that hard of a question. Of all the places you can go for help, you come to a design geared site? And treating people like that isn't going to help.

Moved to School. (where the thread will probably die.)

I think y'all are being a little unfair because other people have asked for help here before too, so why just attack this guy?

Anyway. It's simple stoichiometry.

First you should balance the equation by putting a 2 in front of LiOH.

Convert 71.85 g of LiOH into moles. (71.85g / 23.95g/mol = 3 moles of LiOH)

Convert moles of LiOH into moles of Li2CO3. Mole ratio according to what is given is 2:1 so it would just be 1.5 moles of Li2CO3.

Convert moles of Li2CO3 into grams. (1.5 moles x 73.89 g/mol = 110.8 g of Li2CO3).

Answer: 110.8 g of Li2CO3

Mind you I haven't taken Chem in 2 years so I might be wrong. That is if you check this again.

i think it's fair. if this was a regular posting member asking it then i wouldn't care. it's just the fact this person hasn't done anything on the forums but ask for homework help. i think it's annoying when people come around and don't want to contribute anything and only want someone to do their homework for them.

i don't think i attacked them either way though...i just stated it's not a homework forum _unsure.gif i'm pretty sure i was attacked for pointing that out though.
