Guida verificata passo dopo passo1
Identify the given pressure in mmHg, which is 633 mmHg, and the desired unit, atm (atmospheres).
Recall the conversion factor between mmHg and atm: 1 atm = 760 mmHg.
Set up the conversion equation to convert mmHg to atm: \(\text{Pressure (atm)} = \frac{\text{Pressure (mmHg)}}{760}\).
Substitute the given value into the equation: \(\text{Pressure (atm)} = \frac{633}{760}\).
Perform the division to find the pressure in atm (do not calculate the final value here, just set up the expression).
