Use the formula: Desired Quantity ÷ Current Quantity (or formula quantity). Therefore, 80 g ÷ 100 g = 0.8. You must multiply each ingredient by 0.8 to get the desired quantity. The correct answer is: 0.8
The pharmacy's recipe book provides a formula that yields 15 g of an ointment. You are asked to prepare a 90 g jar of the ointment. By what number do you need to divide each ingredient to make the desired formula?
Use the formula: Desired Quantity ÷ Current Quantity (or formula quantity). Therefore, 90 g ÷ 15 g = 6. You must multiply each ingredient by 6 to get the desired quantity. The correct answer is: 6
You need to prepare a compound of a medication with a concentration of 0.5%. How many grams of the medication will be in 5 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore, 0.5 g ÷ 100 g of product. Next, determine how many grams of the medication will be in 5 g of the final product using the equation: 0.5 : 100 :: x : 5 (0.5 × 5 = 2.5. 100 × x = 100x. x = 2.5 ÷ 100 = 0.025). There will be 0.025 g of medication in 5 g of final product. The correct answer is: 0.025 g
You need to prepare a compound of a medication with a concentration of 10%. How many grams of the medication will be in 50 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore, 10 g ÷ 100 g of product. Next, determine how many grams of the medication will be in 50 g of the final product using the equation: 10 : 100 :: x : 50 (10 × 50 = 500. 100 × x = 100x. x = 500 ÷ 100 = 5). There will be 5 g of medication in 50 g of final product. The correct answer is: 5 g
You need to prepare a compound of a medication with a concentration of 15%. How many grams of the medication will be in 150 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore, 15 g ÷ 100 g of product. Next, determine how many grams of the medication will be in 150 g of the final product using the equation: 15 : 100 :: x : 150 (15 × 150 = 2250. 100 × x = 100x. x = 2250 ÷ 100 = 22.5). There will be 22.5 g of medication in 150 g of final product. The correct answer is: 22.5 g
You need to prepare a compound of a medication with a concentration of 20%. How many grams of the medication will be in 120 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore, 20 g ÷ 100 g of product. Next, determine how many grams of the medication will be in 120 g of the final product using the equation: 20 : 100 :: x : 120 (20 × 120 = 2400. 100 × x = 100x. x = 2400 ÷ 100 = 24). There will be 24 g of medication in 120 g of final product. The correct answer is: 24 g
You need to prepare a compound of a medication with a concentration of 6%. How many grams of the medication will be in 40 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore, 6 g ÷ 100 g of product. Next, determine how many grams of the medication will be in 40 g of the final product using the equation: 6 : 100 :: x : 40 (6 × 40 = 240. 100 × x = 100x. x = 240 ÷ 100 = 2.4). There will be 2.4 g of medication in 40 g of final product. The correct answer is: 2.4 g
You need to prepare a compound of a medication with a concentration of 5%. How many grams of the medication will be in 100 g of the final product?
Use the weight-in-weight formula: x g of medication ÷ 100 g of product. Therefore: 5 g ÷ 100 g of product. The correct answer is: 5 g
You need to prepare a compound of medication using 5 g of active ingredient in 200 g of a cream base. What is the percentage strength of this compounded preparation? Round your answer to the nearest tenth of a percent.
