Answer:
1837.65 mmHg is the pressure in millimeters of mercury.
Explanation:
The expression for the conversion of Pressure (kPa) to pressure (mmHg) is shown below as:-
Pressure (kPa) = 7.501 x Pressure (mmHg)
The pressure value given = 245 kPa
It can be expressed in millimeters of mercury as:-
Pressure = 7.501 x 245 mmHg = 1837.65 mmHg
<u>1837.65 mmHg is the pressure in millimeters of mercury.</u>
