Example Find the gram formula mass of 1 moles of KAl(SO4)2· 12H2O. Remember, multiply the values of atomic mass units of atoms times their subscripts. Coefficients are multiplied by everything that follows. For this example, that means there are 2 sulfate anions based on the subscript and...
The percent yield is also used in the field of chemistry, where the percentage yield of a chemical reaction is considered very important. The formula to calculate the percentage yield is to compare the yield or the quantity of the product that is obtained. Why is the Percent Yield not 100%...
