Weight of a given volume of pure vapor or gas compared to the weight of an equal volume of dry air at the same temperature and volume?
PV = nRT
At a given temperature (T), pressure (P), and volume (V), the number of moles of gas is constant. Thus, whichever gas has a higher molar mass will weigh more. Air is composed of mostly Nitrogen gas (N2), Carbon Dioxide (CO2) and Oxygen gas (O2). The molar masses of these are 28, 44, and 32 respectively.
If the pure vapor or gas in question is water vapor (H2O), with molar mass 18, then the air will weigh more.
What else can I help you with?
Does the same volume of all dry substances weigh the same?
No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
How do you convert the volumen into weight?
To convert volume to weight, you need to know the density of the substance in question. The formula is Weight = Volume x Density. First, find the density of the material, then multiply it by the volume to get the weight.
Is measure milk by volume or weight?
Milk is measured by volume. It is not measured by weight.
How do you find out the volume when you have molecular weight and wt of compound?
To calculate the volume of a compound when given its molecular weight and weight, you need to first convert the weight to moles using the molecular weight. Then, you can use the density of the compound to find the volume by dividing the weight in moles by the density. The formula is volume = weight (in moles) / density.
What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
This is expressed as the weight of a mineral compared with the weight of an equal volume of water?
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
Does the same volume of all dry substances weigh the same?
No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
When is pressure useful?
when determining volume, moles, weight, and/or temperature
What are some non examples of volume?
Time, temperature, and weight are examples of non-examples of volume. Time is a measure of duration, temperature is a measure of heat, and weight is a measure of mass.
What do you mean by air has weight and volume?
Air is made up of particles that have mass, so collectively they have weight. The volume of air refers to the amount of physical space it occupies. This weight and volume can be affected by factors such as temperature and pressure.
What can be measured in the metric system?
Weight, length, temperature, volume, land area.
The ratio of the weight of a given volume of a substance in a vacuum at a given temperature to the weight of an equal volume of water in a vacuum at a given temperature is known as?
This ratio is called the specific gravity.
How do you calculate weight of gasoline in tank?
To calculate the weight of gasoline in a tank, you would need to know the volume of gasoline in the tank and its density. Multiply the volume by the density to get the weight. The density of gasoline can vary depending on factors such as temperature and composition.
Is the Volume gas directly proportional to its molecular weight?
No, the volume of a gas is not directly proportional to its molecular weight. The volume of a gas is mainly influenced by the number of gas molecules present, temperature, and pressure. The ideal gas law equation, PV = nRT, takes into consideration these factors to describe the relationship between volume, pressure, temperature, and the amount of gas.
How do you convert the volumen into weight?
To convert volume to weight, you need to know the density of the substance in question. The formula is Weight = Volume x Density. First, find the density of the material, then multiply it by the volume to get the weight.
Compares weight of minerals with weight of an equal volume of water called?
The weight of a mineral is compared to the weight of an equal volume of water using a measurement called specific gravity. Specific gravity is the ratio of the weight of the mineral to the weight of an equal volume of water. Minerals with a specific gravity greater than 1 are heavier than water, while those with a specific gravity less than 1 are lighter.
How many cc's are in a pound?
CC is unit of volume and lb is unit of weight. These two cannot be compared.
