What is the density of water vapour?
1.27 g/l).
What is the density of water vapor in kg m3?
Hence the specific humidity corresponding to these atmospheric conditions is 0.0107 kg/kg, which says that the water vapor makes up about 1% of the moist air by weight. Hence the vapor density is 0.013 kg/m3.
Is density of water Same as water vapour?
Water vapor is also much less dense than the liquid or the solid. At 100°C and ordinary pressures, its density is 5.98 × 10–4 g cm–3, less than one thousandth that of solid or liquid mercury. A modern chemist would interpret these macroscopic properties in terms of a microscopic model involving molecules of water.
What is the density of water vapor g ml?
Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit). The rounded value of 1 g/ml is what you’ll most often see, though.
How do you calculate vapor density?
It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen. (and thus: molar mass = ~2 × vapour density) For example, vapour density of mixture of NO2 and N2O4 is 38.3.
How do you calculate vapor pressure of water?
Simple formula simple_pressure = e^(20.386 – (5132 / (temperature + 273)) , where vapor pressure is expressed in mmHg and temperature in kelvins.
What is the density of water vapor at boiling point of water?
Explanation: Water density varies with temperature, it never has an absolute value. The density of water vapour at 100°C (boiling point) is 6 × 10-4 g cm-3.
How do you find vapor pressure from density?
To compute a compound’s vapor density simply divide the molecular weight of the compound by the molecular weight of air.
How do you calculate vapor pressure?
In chemistry, vapor pressure is the pressure that is exerted on the walls of a sealed container when a substance in it evaporates (converts to a gas). To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln(P1/P2) = (ΔHvap/R)((1/T2) – (1/T1)).
What is the pressure of steam?
The triple point of H2O, where the three phases of ice, water and steam are in equilibrium, occurs at a temperature of 273.16 K and an absolute pressure of 0.006 112 bar. This pressure is very close to a perfect vacuum.
Is steam more dense than water?
Considering the molecular arrangement of liquids and vapours, it is logical that the density of steam is much less than that of water, because the steam molecules are further apart from one another. The space immediately above the water surface thus becomes filled with less dense steam molecules.
What are the different vapor density and pressure measurements?

What is the saturation pressure and density of water vapor?
Saturation pressure and density of water vapor for common temperatures 1 lb/ft3 = 16.018 kg/m3 1 kg/m3 = 0.0624 lb/ft3 Example – Saturation Pressure Water Vapor
What is the density of water vapor in G mm3?
Density of Water vapor g mm3 = 7.56 × 10 -7 g/mm³ Density of Water vapor lb in3 = 2.73 × 10 -5 lb/in³ See density of Water vapor in hundreds of units of density measurement grouped by weight.
