Answer is: the temperature is 28.9°C.

n = 2.48; amount of the gas.

V = 30.0 L; volume of the gas.

p = 1559 mmHg : 760 mmHg/atm.

p = 2.05 atm; pressure of the gas.

R = 0.0821 L·atm/mol·K.

Ideal gas law: p·V = n·R·T.

T = p·V : (n·R).

T = 302.05 K - 273.15.

T = 28.9°C; temperature of the gas.
