Grade 11 Stoichiometry help So I'm stuck on this question (I got the answer for the first part of the question, but not the second) and I was wondering if anyone knew how to complete the second part? The chemical formula: 2KCl(aq) + 1Pb(NO3)2(aq) ----> 1PbCl2(s) + 2KNO3(aq) + 215 kJ The question: A 59.0% pure sample of Pb(NO3)2 which has a mass of 6.5g reacts with excess KCl. What mass of KNO3 could I produce? If I run this experiment in a 2.0L vessel, what will be the molar concentration of the resulting KNO3(aq) solution?

Stuck on login and worlds dont show So I haven't played Maple in a month or two, so I decided to log in just for the anniversary. I usually use Game Launcher, but when I used it and pressed the login button, it was just stuck there (the login screen). I tried to launch it from the website after, and when the game started, it showed none of the worlds and I was disconnected like 30 seconds after. I was wondering if this happened to anyone else and if there is a fix for it? The OS is Win8 btw.
