Identify the conversion factor between atmospheres (atm) and millimeters of mercury (mm Hg). The standard conversion is \(1\ \text{atm} = 760\ \text{mm Hg}\).
Set up the conversion equation to find the equivalent pressure in mm Hg by multiplying the given pressure in atm by the conversion factor: \(P_{\text{mm Hg}} = P_{\text{atm}} \times 760\).
Substitute the given pressure value into the equation: \(P_{\text{mm Hg}} = 0.905 \times 760\).
Perform the multiplication to calculate the pressure in mm Hg (do not provide the final numerical answer here, just the operation).
Compare the calculated value with the given options to identify the correct equivalent pressure in mm Hg.
