Specific volume. Specific volume for an ideal gas is also equal to the gas constant (R) multiplied by the temperature and then divided by the pressure multiplied by molar mass of that ideal gas.
In this way, how do you find the specific volume of a mixture?
To calculate specific volume you need to know the volume (V) and the mass (m). Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.
Secondly, how do you find the volume of a gas? Molar volume of gases
- volume = 0.5 × 24 = 12 dm 3
- Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
- The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known:
- number of moles = volume of gas at rtp ÷ 24.
People also ask, how do you find the gas constant of a mixture?
The specific gas constant of a gas or a mixture of gases (R specific ) is given by the molar gas constant divided by the molar mass (M) of the gas or mixture. R(specific) = R/M. reference- Gas constant – Wikipedia.
What is specific air volume?
Specific volume is defined as the total volume of dry air and water vapor mixture per kg of dry air and water vapor (SI-units). The specific volume can be expressed as: v = V / ma + mw (11)

What is the value of R?
The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K. R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.
How do I find the volume?
Units of Measure Volume = length x width x height. You only need to know one side to figure out the volume of a cube. The units of measure for volume are cubic units. Volume is in three-dimensions. You can multiply the sides in any order. Which side you call length, width, or height doesn’t matter.
What is specific volume of water?
The specific volume (ν) of a substance is the total volume (V) of that substance divided by the total mass (m) of that substance (volume per unit mass). It has units of cubic meter per kilogram (m3/kg). Changes of Density. In general, density can be changed by changing either the pressure or the temperature.
What is the symbol for specific volume?
Specific Volume. It is defined as the property of a material in which the substance of one kilogram contains the number of cubic meters. The unit of specific volume is m 3 / kg and it is represented by the symbol v.
What is the unit weight of water?
In the metric, or SI, system the unit weight of water is 998 kg per cubic meter — kg/m3 — or approximately 1 g per cubic centimeter, g/cm3. In imperial measurements, the unit weight of water is commonly given as 62.4 pounds per cubic foot, lbs/ft3.
What is PV nRT called?
PV = nRT: The Ideal Gas Law. Fifteen Examples Each unit occurs three times and the cube root yields L-atm / mol-K, the correct units for R when used in a gas law context. Consequently, we have: PV / nT = R. or, more commonly: PV = nRT. R is called the gas constant.
What is specific volume of soil?
It is the reciprocal of density and an intrinsic property of matter as well. Specific volume is defined as the number of cubic meters occupied by one kilogram of a particular substance.
What is an example of a gas mixture?
Gas Mixtures. For example, the air we breathe is a mixture of several gases. It is mostly nitrogen and oxygen, but water vapor, argon, carbon dioxide, and various other gases are also present in small amounts.
What is the R constant in the ideal gas law?
The gas constant R is 8.314 J / mol·K. Convert the numerical value of R so that its units are cal / (mol·K). A unit conversion table will tell you that 1 cal = 4.184 J.
What is the R in the ideal gas law?
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.
What is a gas mixture?
Mixture of gases are common in many applications. Our most common example is air – mainly consisting of nitrogen, oxygen and water vapor – as moist air. A combustion gas with nitrogen, water vapor and carbon dioxide is an other example.
What is meant by the gas constant?
Definition of gas constant. : a general constant in the equation of state of gases that is equal in the case of an ideal gas to the product of the pressure and volume of one mole divided by the absolute temperature — see gas law sense c.
