What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
How do you calculate the relative molecular mass of H2O WATER?

The relative molecular mass of water?
Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.
A compound formed of 0.059 mol hydrogenand 0.94 mol oxyegn has a molecular mass of 34.0what is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 1:1. This means the compound is water (H2O), which has a molecular mass of 18.0 g/mol, not 34.0 g/mol. The given molecular mass of 34.0 g/mol does not match the properties of water.
What is the molecular mass of cytosine?
The molecular mass of cytosine is approximately 111.1 grams per mole.
Is the mass diffusivity of air in water vapour equal to that of water vapour in air?
No, the mass diffusivity of air in water vapor is different from the mass diffusivity of water vapor in air. The diffusivity of a substance in a medium depends on various factors such as temperature, pressure, and molecular weights of the substances involved, leading to different diffusion rates in different directions.
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.
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
Word for floating mass of water vapour?
Cloud.
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.
Which product has the largest molecular mass sodium acetate water or carbon dioxide?
Sodium acetate has a larger molecular mass than water or carbon dioxide. Water has a molecular mass of 18 g/mol, carbon dioxide has a molecular mass of 44 g/mol, and sodium acetate has a molecular mass of 82 g/mol.
What has more mass water or sulfuric acid?
The molecular maass of sulfuric acid (98,08) is greater than the molecular mass of water (18).
Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
What does h20 represent?
H2O represents the molecular formula of water (liquid state), ice (solid state) or water vapour (gaseous state).
Does water have a mass of 18 grams?
It is water's molecular weight or mass number that equals 18 atomic mass units
What refers to the amount of water vapour in the air?
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
