What is the molecular weight of air in lb lbmol?
The molecular weight of air is approximately 28.97 lb/lbmol.
What is the molecular weight of air in pounds per pound-mole?
The molecular weight of air is approximately 28.97 pounds per pound-mole.
Molecular weight of air at standard conditions?
First, molecular weight is a direct function of the level of dissociation and hence an indirect function of temperature. Dissociated Air has a significantly (about an order or magnitude) lower molecular weight as associated air (e.g. air at room temperature). Dissociation for air starts somewhere around 2000 Celsius (that's where O2 goes into O+O) and hence, the molecular weight of air up to 2000 Celsius is constant. This also affects the "specific gas constant" which drastically decreases in temperature regimes where dissociation occurs.With that said, the molecular weight of DRY air (no water vapor) is 28.97. Engineering Toolbox does a good job of breaking down the composition of associated air, see the URL below:http://www.engineeringtoolbox.com/molecular-mass-air-d_679.html

Why molecular weight of air is 28.9?
It is the weighted average of the individual molecular weights of the components oxygen and nitrogen. Generally speaking, air is composed of 21% oxygen and 79% nitrogen. Thus the average molecular weight of air is calculated as follows: MW air = (.21)*(MW O2) + (.79)*(MW N2)

Why is water vapor lighter than air?
Water evaporated at atmospheric pressure is 1601 times less dense than liquid water. Air is 1225 times less dense than liquid water.Nitrogen gas the primary component of air has a molecular weight of 28.014.Oxygen the secondary component of air has a molecular weight of 31.998.Water has a molecular weight of 18.015. Water is lighter in the gaseous state.
How quickly gas spreads in air?
The diffusion rate of gas in air depends on factors like temperature, pressure, and molecular weight of the gas. Gases with lower molecular weight tend to diffuse faster than those with higher molecular weight. In general, gas molecules will spread throughout the air relatively quickly due to their high mobility and ability to mix freely.
Why is the gas sulfur hexafluoride heavier then air?
The density of a gas is propotional to its molecular weight. Air is composed of primarily of nitrogen and oxygen, which have molecular weights of about 28 g/mol and 32 g/mol respectively. Sulfur hexafluoride has a molecular weight of about 146 g/mol, which would make it roughly 5 times denser than air.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
What is the molecular weight of vanillideneacetone?
The molecular weight of vanillideneacetone is 192.214g/mol.
