Question

1 doz Mg 4B89Mg x-ㄧㄧ 2502 g ㄨ ㄧ 550gMq 1 doa Mg Step 2) Predicted Your calculation Predicted mass of MgCia as possibile, using ONLY the Mg atoms that you weighed out in Step 4 (if you weighed 9 you can build 9 MgCle molecules.) Weigh the MgCih molecaules and record the mass. Your predicted mass 5. Now, BUILD as many MgClh molscuies Mg atoms in Stop 4, of MgClh should agree with the actual mass ot MgClg within a lew tenths of a gram Actual mass of MgCy molecules from 5 grams Mg previous example assumed that onough chlorine atoms were availatble to build the MgCly molecules. What if this wasn't rue? This is a lmting reactant problem: what mass of MgCl molecules can be bult trom 3.79 g Mg and 8.20 g CI? Weigh (as closely as possible) 3.79 g Mg and 8.26 g Cl and record the masses below. 6. The Mass of Mg used(about 3.79 g g (about 826 g) Mass of Cl used TWO separate calculations: one based on Mg and MgClg, the other based on Ci and MgClh Follow the example calculasions below, but use the values you have recorded on this lab report. Predict the amount of MgCl2 that can be made trom these amounts of Mg and CL. This is just like Stop 4 but you have to make 1 doz Mgc, 25.02 g MgC, 1 doz Mg 17.24 gMgo, ㄨㄧㄧㄧㄨㄧ 179 g Mg× ー 5.50g Mg 1 doz Mg 2502 g Mgc 1 doz Maci, 1 doz Mgcl, 10.50g 1050gC 2 dor a Your caloulation for Mg Predicted mass of MgCi2 Your calculation for C Predicted mass of MgCb
