Question

Under constant pressure, when a 30.8 L of a gas is warmed from 119 degree C, what is the final volume (in L)? When 0.88 atm of methane reacts with 1.496 atm of oxygen at a constant temperature in a closed rigid container to form carbon dioxide and water vapor, what is theoretical yield (on atm) of carbon dioxide? When 42 L on nitric oxide reacts with 40.9 L of oxygen at 410 K under a constant pressure of 1.487 atm, what is the theoretical yield (in g) of nitrogen dioxide? What mass (in g) of nitrogen must be added to 9.73 g of argon at 24.38 degree C, and in a 122 L contain for a final pressure of 915 mmHg?

Explanation / Answer

Vi = 30.8 L

Ti = 119 oC = (119+273) K= 392 K

Tf = 241 oC = (241 +273) K = 514 K

Vf = ?

since P is constant,

use:

Vi/Ti = Vf/Tf

30.8 / 392 = Vf/514

Vf = 40.4 L

Answer: 40.4 L
