dyke 270 Posted March 14, 2014 Share Posted March 14, 2014 Here's the question: When chlorine is added to acetylene, 1, 1, 2, 2-tetrachloroethane is formed:2 Cl2 (g) + C2 H2 (g) --> C2 H2 Cl4 (l)How many liters of chlorine will be needed to make 75.0 grams of C2 H2 Cl4? Apparently, the answer is 21.8L, but shouldn't it be 20L? Also, if you can find gas stoichiometry problems for me (Including the answers) i'll give you 100k won Link to comment Share on other sites More sharing options...
Sulliverse 288 Posted March 14, 2014 Share Posted March 14, 2014 20,1L are needed Link to comment Share on other sites More sharing options...
dyke 270 Posted March 14, 2014 Author Share Posted March 14, 2014 It's 20,1L How'd you get 20.1l? Link to comment Share on other sites More sharing options...

Athena 21,718 Posted March 14, 2014 Share Posted March 14, 2014 How'd you get 20.1l? For stoichiometry isn't it: 75.0g C2H2Cl4 x (1 mol C2H2Cl4 / 168g C2H2Cl4) x (2 mol Cl2 / 1 mol C2H2Cl4) x (22.4L Cl2 / 1 mol Cl2) Link to comment Share on other sites More sharing options...
초췌 270 Posted March 14, 2014 Share Posted March 14, 2014 i got 20.0 assuming stp Link to comment Share on other sites More sharing options...

dyke 270 Posted March 14, 2014 Author Share Posted March 14, 2014 Using my equation above I got 20.2L Shouldn't the mass for c2h2cl4 be 167.84g? Link to comment Share on other sites More sharing options...
Athena 21,718 Posted March 14, 2014 Share Posted March 14, 2014 Shouldn't the mass for c2h2cl4 be 167.84g? Your'e right I was just using gram molecular mass to estimate. I just got 20.0L like you. Link to comment Share on other sites More sharing options...

Klover12 563 Posted March 14, 2014 Share Posted March 14, 2014 OMG, I WAS ON THIS UNIT LIKE 4 LESSONS AGO. Our teacher cannot teach but he gave us a flow chart of what to do that helped us tremendously... Link to comment Share on other sites More sharing options...
Tonbo de Corn 254 Posted March 14, 2014 Share Posted March 14, 2014 since they're asking liters shouldn't you convert the mass chlorine that you got from stoichiometry by using the density of chlorine? Link to comment Share on other sites More sharing options...
