Answer:
1.68 atm
Step-by-step explanation:
Applying
P/T = P'/T'................... Equation 1
Where P = Initial pressure, T = Initial Temperature, P' = Final pressure, T' = Final Temperature.
Make P' The subject of the equation
P' = PT'/T.............. Equation 2
From the question,
Given: P = 2.25 atm, T = 125°C = (125+273) K = 398 K, T' = 25°C = (25+273) K = 298 K.
Substitute these values into equation 2
P' = (2.25×298)/398
P' = 1.68 atm
