Step 1: Find The Mass (Amount) Of Each Element In The Compound We start the procedure by finding the exact amount (in grams) of each element that makes up the compound being studied. Let’s assume that the compound whose empirical formula is to be found is XaYbZc. Chemical analysis of...
How do you find theoretical and percent yield? Theoretical Yield: the given reactant amount in grams multiplied by the molecular mass of the product in grams/mole and the molecular mass of the limiting reactant in grams/mole. The theoretical yield is used in the formula to find the percent...
To figure out how many grams of protein you should be eating, there's a simple formula, courtesy ofAmerican College of Sports Medicine, that you can use: Divide your weight in pounds by 2.2 to get your weight in kilograms. Multiply that number by 1.2 and 1.7 for a recommended protein ra...
