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
