Convert 453. mmHg to atm . Be sure your answer has the correct number of significant figures. Note: Reference the Conversion factors for non-SI units table for additional information.

To convert mmHg to atm, you can use the conversion factor where 1 atm is equivalent to 760 mmHg. So, you take your measurement of 453 mmHg and divide it by 760 mmHg/atm: 453 mmHg × (1 atm / 760 mmHg) = 0.595 atm. Since your initial measurement of 453 mmHg has three significant figures, your final answer should also be reported with three significant figures, resulting in 0.595 atm. Remember, when working with significant figures, the least number of significant figures in any of the measurements dictates how many figures you should carry through to your final answer!
