Answer

Explanation:

Step1: Convert mmHg to atm

Use the conversion factor $\frac{1\ atm}{760\ mmHg}$. So the pressure in atm is $P_{atm}=725\ mmHg\times\frac{1\ atm}{760\ mmHg}$. $P_{atm}=\frac{725}{760}\ atm\approx0.9539\ atm$

Step2: Convert atm to kPa

Use the conversion factor $101.325\ kPa/atm$. So the pressure in kPa is $P_{kPa}=0.9539\ atm\times101.325\ kPa/atm$. $P_{kPa}=0.9539\times101.325\ kPa\approx96.6\ kPa$

Answer:

Step 1: $0.9539\ atm$ Step 2: $96.6\ kPa$
