Final answer:
The typical magnesium content in a human body is about 21 grams, with 70% of it residing in bones and the rest in soft tissues and body fluids. For a 60-kg adult, it's expected that they have a magnesium amount close to this typical content.
Step-by-step explanation:
The question relates to the amount of magnesium present in an adult's body. Approximately 70% of magnesium in the body is found in bone, complexed with calcium and phosphorus, with the remainder distributed throughout soft tissues and body fluids. Magnesium plays a critical role as the principal cation in soft tissue. The typical magnesium content in a human body is about 21 grams; hence, a 60-kg adult typically contains an amount close to this figure. However, this can vary depending on factors such as dietary intake and overall health.
