The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.

Can density be seen?
Density is not a visual quality. But we can infer information about density by observing. For example moist air is lighter than dry air - that is why the clouds condense at higher altitudes, not at ground level. {Explanation - H2O has an molecular mass of 28; O2 has an molecular mass of 32; N2 has an molecular mass of 34. Hence H2O vapour is lighter than O2 or N2.}
What is vapour density of air?
The vapor density of air is the ratio of the mass of a certain volume of air to the mass of an equal volume of a reference gas, typically hydrogen or dry air. It is used to compare the density of a gas to that of another gas or to the average molecular weight of air. The vapor density of air is approximately 1.29, meaning that air is slightly heavier than the reference gas hydrogen.
What is the relationship between velocity and molar mass in gases?
mole is short for molecular. they are basically one in the same. the molecular mass is in amus, the average mass unit, and the mole is a number that converts amus to grams. a mole is the amount of particle in 12 grams of carbon-12, best explained by avagadros number: 6.022*10^23. this is to say molecular mass is the mass of a molecule, and the molar mass is the amount of moles. so there would be 10 moles in 10 grams of Hydrogen. and a molecule of hydrogen, H2, would be 2.014 amu.
What changes in molecular attraction occur as water goes from a solid to a liquid to a gas?
The changes occuring in molecular attraction as water goes from a solid to a liquid is that the bonds between the molecules weaken and the molecules move further away from each other. Once they become a gas, their bonds break and the molecules float freely around.
Which one has high vapour pressure water or alcohol?
Alcohol typically has a higher vapor pressure than water at a given temperature due to its lower molecular weight and weaker intermolecular forces. This means that alcohol evaporates more readily than water.
How is molecular mass and vapour density related?
density is mass per unit volume, meaning that as mass increases ,the density increases. Unlike volume, as it increases the density decreases.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
The vapour density of a gas is 11.2 so the volume occupied by 11.2 gm of the gas at NTP is?
vapour density of a gas= mass of a substance at STP/mass of a hydrogen at STP11.2= 1 gm molecule of a substance/2g11.2*2=1 gm molecule of a substance22.4g=1 gm molecule of a substance22.4g occupies Lt. at STPtherefore 11.2g occupies Lt.*11.2g/22.4g=11.2Lt.
Vapour density of Oxygen?

Vapour Density of Hydrogen?

How is vapor density and firefighting similar?
There is no similarity between vapor density and firefighting - one is a measure of the density of a gas or vapour relative to another (often Hydrogen or air) and the other is heroic job.
Is there any mathematical relationship for the effect of temperature on hydrocarbon density?
With increase in temperature , the density of fluids decreases and their vapour pressure increases. There's no direct relationship for temp-density of HYdrocarbons. But temperature and density are inversely proportional and the constant of proportionality varies from fluid to fluid. For hydrocarbons that constant can be calculated keeping in mind its VP, boiling point at ambient conditions and its constituents.
Why do you think ice has a higher density than water vapour?
Because ice is solid and has a heavier weight that cause it to have higher density and as for water vapour, it is gaseous and has lower density due to not having any weight.
How ostwald and walker method can be used to find out molecular weight?
A strem of dry air is bubbled through the solution & solvent from the loss in weight of solvent & solution the relative loweing of vapour pressure calculated. From relative lowering of vapour pressure molecular weight is calculated. anupama
What is the density of acetone vapour at 98.5 degree Celsius?
Density is the quantity of matter present in a unit of volume. It is denoted by D. The SI unit for density is kg/m^3. The density of acetone vapour is 0.86 kg/m^3 at 98.5 degree Celsius.

The empirical formula of a compound is ch2oits vapour density is 45calculate its molecular formula?
To determine the molecular formula from the empirical formula and the vapor density, we first need to calculate the empirical formula mass. The empirical formula mass of CH2O is 12g (carbon) + 2g (hydrogen) + 16g (oxygen) = 30g/mol. Next, we compare the vapor density with the empirical formula mass to find the factor by which the empirical formula mass is multiplied to get the molecular mass. The factor is 1.5 (45 / 30 = 1.5). Finally, we multiply the subscripts in the empirical formula by this factor to get the molecular formula, which is C3H6O3.
