Chapter 23.4, Problem 26R

To determine

To Calculate: The mass of protein in a person’s body in kilograms.

Answer to Problem 26R

The mass of the protein in a person’s body, whose mass is $50\text{ kg}$ , is $7.5\text{ kg}$ .

Explanation of Solution

Given data:

Percent of protein in human body is $15\%$ .

Calculation:

As per the problem,

Consider the person’s mass to be $50\text{ kg}$ .

Percent of protein in human body is $15\%$ , that is, $15\%$ of the mass of a person is protein.

Therefore, mass of the protein in the person’s body is

  $\begin{array}{l}=15\%\times 50\text{ kg}\\ =\frac{15}{100}\times 50\text{ kg}\\ =7.5\text{ kg}\end{array}$

Conclusion:

The mass of the protein in a person, whose mass is $50\text{ kg}$ , is $7.5\text{ kg}$ .
