Use Factor Method in solving the problems: Step 1. Using the following equation, determine the factor that defines the multiple or the decimal fraction of the amount of formula to be prepared: Quantity of formula desired/Quantity of formula given = Factor
Use Factor Method in solving the problems:
Step 1. Using the following equation, determine the factor that defines the multiple or the decimal fraction of the amount of formula to be prepared:
Quantity of formula desired/Quantity of formula given = Factor
A factor greater than 1 represents the multiple of the formula, and a factor less than 1 indicates the fraction of the formula to be prepared.
Step 2. Multiply the quantity of each ingredient in the formula by the factor to determine the amount of each ingredient required in the reduced or enlarged formula.
1. From the following formula, calculate the quantity of each ingredient required to make 1 gallon of compound benzoin tincture.
