A closed container with a capacity of 1 liter contains gas with a mass of 16 g. Find the gas pressure at 27 ° C if the gas is oxygen.

To estimate the magnitude of the oxygen pressure in the taken closed vessel, we use the Mendeleev-Clapeyron equation: P = m * R * T / (MO2 * V).

Constants and variables: m – gas mass (m = 16 g); R – universal gas constant (R = 8.31 J / (K * mol)); T – considered absolute temperature (T = 300 K); MO2 – molar mass (MO2 = 32 g / mol); V is the volume of a closed vessel (V = 1 l = 10 ^ -3 m3).

Let’s calculate: P = m * R * T / (MO2 * V) = 16 * 8.31 * 300 / (32 * 10 ^ -3) = 1246.5 * 10 ^ 3 Pa.

Answer: The pressure is 1246.5 kPa.
