In a room measuring 10x5x3 m3, the temperature is maintained at 293 K, and the dew point at 283 K.

In a room measuring 10x5x3 m3, the temperature is maintained at 293 K, and the dew point at 283 K. Determine the mass of water vapor contained in the room. The density of saturated vapors is 9.4 g / m3 at 283 K and 17.3 gm / m3 at 293 K.

To find the value of the mass of water vapor contained in the specified room, we use the formula: m = ρн * V = ρн * a * b * h.

Data: ρн – density of saturated vapors at Т = 283 K (ρн = 9.4 g / m3); a – the length of the specified room (a = 10 m); b is the width of the room (b = 5 m); h – height (h = 3 m).

Let’s perform the calculation: m = ρн * a * b * h = 9.4 * 10 * 5 * 3 = 1410 g.

Answer: This room contains 1.41 kg of water vapor.
