Chapter SH, Problem 17.8APP

To determine

To calculate:The percentage of nitrogen in the human body.

Answer to Problem 17.8APP

The percentage of nitrogen in the human body is $3\%$ .

Explanation of Solution

Given data:

On a circle graph showing the percentage of elements in the human body, the wedge representing nitrogen takes up ${10.8}^{\text{o}}$ .

Formula used:

In a circle graph, ${360}^{\text{o}}=100\%$ .

Calculation:

As per the problem,

The angle representing nitrogen in the human body on the circle graph $={10.8}^{\text{o}}$

Convert ${10.8}^{\text{o}}$ into percentage using the conversion factor

  $\begin{array}{l}{360}^{\text{o}}=100\%\\ 1^{\text{o}}=\frac{100}{360}\%\\ {10.8}^{\text{o}}=\frac{10.8}{360}\times 100\%\\ =3\%\end{array}$

Conclusion:

The percentage of nitrogen in the human body is $3\%$ .
