Chapter 4, Problem 15c
Using the Chemistry Link to Health: Elements Essential to Health, answer each of the following:
c. How many grams of sulfur would be a typical amount in a 60.-kg adult?
Verified step by step guidance1
Identify the percentage of sulfur in the human body from the Chemistry Link to Health: Elements Essential to Health. For example, sulfur might make up approximately 0.2% of the human body by mass.
Convert the percentage of sulfur into a decimal for calculation purposes. For instance, 0.2% would be written as 0.002.
Determine the total mass of the adult in kilograms, which is given as 60. kg in the problem.
Calculate the mass of sulfur in the body by multiplying the total body mass by the decimal form of the sulfur percentage. Use the formula: .
Ensure the result is expressed in grams. Since the body mass is given in kilograms, convert the sulfur mass from kilograms to grams by multiplying by 1000 (1 kg = 1000 g).
