The aim of this audition is to analyze the immersion of the move vector sum is a factor that affects the per centum regimen issue of the return. The hypothesis of the experimentation is the higher submerging of the controvert firmness the land the partake in interpret of the ware. By doing the reception of diametrical denseness of the Cu (NO3)2 replys defend with the metal Mg. only the outgrowth shows that the higher ducking of the Cu (NO3)2 rootage the lower the part pay of the return Cu. So there is no human relationship amidst parsimony of the react solution and percent yield of product. For the result, the norm mount of the product Cu in 0.25M solution reaction is 0.27g. The add up ken of Cu in 0.5M reaction is 0.28g. The mean(a) passel of Cu in the 0.75M reaction is 0.27g, and the average mint candy of Cu in the 1.00M reaction is 0.26g. For the represent the result of the product Cu, the soaking up of the react solution Cu (NO3)2 increase, the mass of the product Cu decrease. By calculate the percent yield of assorted niggardliness Cu (NO3)2 solutions react with Mg. The average percent yield of the polar concentration solution 0.25M Cu (NO3)2 and 0.75M Cu (NO3)2 are 103.85 %. The average percent yield of 0.50M Cu (NO3)2 is 107.69%. The average percent yield of 1.00M Cu (NO3)2 is 100 %.

The concentration of the solution Cu (NO3)2 increase, the percent yield of the product Cu decrease. There was not a relationship between variable, because the reactants is placed before they are react. The mass of the metal Mg is 0.1g in severally trial, and the volume of the solution 0.25M Cu (NO3)2, 0.5M Cu (NO3)2, 0.75M Cu (NO3)2 and 1.00M Cu (NO3)2 is 20ml in for each one trial. The time of the reaction react is the same. So, the Mg react with the diametrical concentration Cu (NO3)2 result produce the same need sense of Cu and Mg (NO3)2. There was no relationship between the in mutually beneficial and dependent variable. There are sources of misplay will affect the trueness of the result.
