Answer:
526 K
Explanation:
Applying pressure law,
P/T = P'/T'...................... Equation 1
Where P = initial pressure of the gas, T = Initial temperature of the gas, P' = Final pressure the gas, T' = Final temperature of the gas.
make T' the subject of the equation
T' = TP'/P............. Equation 2
Given: T = 275 K, P = 835 mmHg, P' = 2.1 atm = (2.1×760) mmHg = 1596 mmHg.
Substitute these values into equation 2
T' = 275(1596)/835
T' = 438900/835
T' = 525.6
T' ≈ 526 K.
Hence the right option is 526 K
