From the following formula, calculate the quantity of each ingredient required to make 1 gallon of compound benzoin tincture. Benzoin 100 g ? Aloe 20 g ? Storax 80 g ? Tolu balsam 40 g ? Alcohol, to make 1000 mL 1 gallon 1 gallon = 3785 mL *Note: Give your final answer in 2 decimal places. Indicate the unit. check_circle
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.

An infant needs 10 mg/kg of an antibiotic. The infant weighs 11 lbs. The antibiotic is available as a 100 mg/10 mL suspension.
- What is the weight of the infant in kilograms (kg)?
- How much antibiotic in milligrams (mg) is needed by the infant?
- How many milliliters (mL) of suspension is needed to be administered to the infant per dose?

Since you have asked a question with multiple subparts, we will answer only first three subparts for you. In order to get other subparts answered, kindly repost complete question specifying the subparts to be answered.
Answer 1
Mass of infant = 11 lbs
Conversion factor is 1 lb = 0.454 kg
Mass of infant (kg) = 11 lb * 0.454 kg/lb
= 4.99 kg
Hence, mass of infant is 4.99 kg.
Answer 2
Antibiotic required is 10 mg/kg
For 4.99 kg, antibiotic required = 4.99 kg * 10 mg/kg
= 49.9 mg
Hence, antibiotic required by infant is 49.90 mg.
Answer 3
Concentration of available antibiotic suspension = 100 mg/10 mL
So, 100 mg antibiotic is contained in 10 mL suspension.
49.90 mg antibiotic will be contained in volume = 49.90 mg * 10 mL/100 mg
= 4.99 mL
Hence, 4.99 mL of antibiotic suspension is required by infant per dose.
