Chapter 5, Problem 1P

Interpretation Introduction

Interpretation: The pressure of oxygen tank in a hospital respiratory unit is 4840 mm Hg. The pressure of the oxygen gas needs to be determined in atmospheres.

Concept Introduction: Unit conversion is a process that involves division or multiplication using a numerical factor which results in the conversion of one unit to other. It also involves the selection of correct number of significant digits and rounding.

Explanation of Solution

The given pressure of oxygen gas is 4840 mm Hg.

The conversion factor required to convert pressure in mm Hg to atm is as follows:

$1\text{atm}=\text{760 mm Hg}$

Thus,

$\begin{array}{c}P=4840\text{mm Hg}\left(\frac{1\text{atm}}{760\text{mm Hg}}\right)\end{array}$

  $\begin{array}{c}=6.368\text{atm}\end{array}$

Conclusion

Thus, the pressure in atm is $6.368\text{atm}$ .
