Overview
I uploaded the lab manual and lab format. You should write a lab report in same with lab format. In conclusion part we need to find percent yield. Just put the calculations below
1.25 g . 1mol/98g= 0.013mol
0.13 x 146g /1mol= 1.9 g
0.77g-0.18g= 0.59 g
Percent Yield=Actual Yield/ Theoretical Yield x 100%
= 0.59 / 1.9 x 100%
= %31.05
