Answer: The volume of the diver's at the same depth, at a temperature of 21.0°C and a pressure of 141.20 kPa is 1.66 L
Step-by-step explanation:
The combined gas equation is, 
 
where, 
 = initial pressure of gas = 101.30 kPa
 = final pressure of gas = 141.20 kPa
 = initial volume of gas = 2.40 L
 = final volume of gas = ?
 = initial temperature of gas = 
 
 = final temperature of gas = 
 
Now put all the given values in the above equation, we get: 
 
 
 
The volume of the diver's at the same depth, at a temperature of 21.0°C and a pressure of 141.20 kPa is 1.66 L
