I need to figure out the diopter.
Please check my work? I first changed Kp to Kc: .900atm(0.0821)(25+273.15)^(2.0 mol*1.0 mol)- (3.0)= 22.03 Than i did an ICE table. I than used the equation Kc= So2Cl2/So2*Cl2. 22.03=(.75+x)/(.5-x)(.25-x). I than solved for x. x=.169 was the only value
How do you change Kp to Kc?
I first changed the 3.59g of AgCl into moles and than divided by liters given to get .0200M of Agcl. I also changed the mol of H20 and LaCl3 to Molarity as well. I got .01M for LaCl3 and.02 for H20. Than I plugged into equation Kc=(.0200)/(.010)(.02). To
