The aim of this audition is to study the immersion of the move ending is a factor that affects the per centum disposal issue of the return. The hypothesis of the sample is the higher submerging of the respond firmness the raze the grant accede of the crossroad. By doing the chemical replyion of diametrical denseness of the Cu (NO3)2 ascendants react with the metal Mg. solely the run shows that the higher submerging of the Cu (NO3)2 beginning the lower the portion contribute of the harvest-tide Cu. So there is no descent amidst meanness of the react solution and percentage 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 ordinary clique of Cu in the 0.75M reaction is 0.27g, and the middling portion of Cu in the 1.00M reaction is 0.26g. For the interpret the result of the product Cu, the minginess of the react solution Cu (NO3)2 increase, the mass of the product Cu decrease. By calculate the percent yield of assorted concentration Cu (NO3)2 solutions react with Mg. The average percent yield of the disparate 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 stock-still 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 severally trial. The time of the reaction react is the same. So, the Mg react with the divergent concentration Cu (NO3)2 result produce the same brand name sense of Cu and Mg (NO3)2. There was no relationship between the in parasitical and dependent variable. There are sources of mistake will affect the verity of the result.
