What is the relationship between molecular mass and vapour density?
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.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
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.}
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.
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.
How do you find the molecular mass when you have STP and density?
mom
What is related to density?
Density = mass/volume so it is related to mass and volume. And Volume is related to temperature and pressure, so it is related to those as well.
How does molecular mass and formula mass are related to the mass of a compound?
t
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.
How is mass related to density?
Matter is in density.
What are mathematical formulas to explain how mass volume and density are related?
Density = mass/volume Mass = (density) x (volume) Volume = mass/density
