Parker Goodman · Answer 1

To determine the pressure in units of kPa, we need to use a conversion factor to convert the units from mmHg to kPa. A conversion factor is a value that would relate two different units and is multiplied or divide to the original measurement depending on what is units is asked. From literature, 1 atm is equal to 760 mmHg and it is also equal to 101.325 kPa. We use these factors to convert the given value. We do as follows:

2150 mmHg (1 atm / 760 mmHg) (101.325 kPa / 1 atm) = 286.643 kPa

Therefore, the closest value from the choices is the second one which has the value of 287, this would be answer.
