Question

the atmospheric pressure at the summit of denali in alaska was measured at 613 mm hg on a certain day. what is this pressure in atmospheres? report your answer with the correct number of significant figures.

Explanation:

Step1: Identify the conversion factor

The conversion factor between mmHg and atmospheres is \(1\space atm = 760\space mmHg\).

Step2: Set up the conversion equation

Let \(x\) be the pressure in atmospheres. We have the equation \(x=\frac{613\space mmHg}{760\space mmHg/atm}\).

Step3: Calculate the value

\(x = \frac{613}{760}\approx0.807\)

Answer:

\(0.807\space atm\)
