Determine the temperature of ammonia NH3 gas, under a pressure of 2.1 * 10 ^ 5 Pa

Determine the temperature of ammonia NH3 gas, under a pressure of 2.1 * 10 ^ 5 Pa, if its volume is 0.02 m ^ 3, and its mass is 0.03 kg.

Data: P (ammonia pressure) = 2.1 * 10 ^ 5 Pa; V (volume occupied by ammonia) = 0.02 m3; m (mass of ammonia taken) = 0.03 kg.

Constants: M (molar mass of ammonia) = 0.017 kg / mol; R (universal gas constant) = 8.31 J / (mol * K).

The temperature of the ammonia gas is determined according to the Mendeleev-Clapeyron law: P * V = (m / M) * R * T and T = P * V * M / (m * R).

Let’s make the calculation: T = 2.1 * 10 ^ 5 * 0.02 * 0.017 / (0.03 * 8.31) = 286.4 K.

Answer: Ammonia gas has an absolute temperature of 286.4 K.
