WebStep 1: Identify the major compound in the sample. The student is checking the purity of silver nitrate. That is the major compound in the sample. Step 2: Determine the chemical … WebStep 4: Calculate the percent purity. Substituting the calculated mass into the equation for percent purity gives: %purity = mass of compound mass of sample × 100 = 3.3 3.5 × (100) = 94.3% % purity = mass of compound mass of sample × 100 = 3.3 3.5 × ( 100) = 94.3 %. This section includes a recommended experiment for informal assessment. WebIn decision tree construction, concept of purity is based on the fraction of the data elements in the group that belong to the subset. A decision tree is constructed by a split that divides the rows into child nodes. If a tree is considered "binary," its nodes can only have two children. The same procedure is used to split the child groups. evolve cleansing melt
