## How do you find the specific volume of a substance?

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.

## What is specific volume of a substance?

Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m3/kg or m3·kg−1). If the density of a substance doubles, its specific volume, as expressed in the same base units, is cut in half.

What is the formula of volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

### How do you find volume in PV nRT?

V = nRT/p = 40 * 8.3144598 * 250 / 101300 = 0.82 m³ ….Ideal gas law equation

1. p is the pressure of the gas, measured in Pa;
2. V is the volume of the gas, measured in m³;
3. n is the amount of substance, measured in moles;
4. R is the ideal gas constant; and.
5. T is the temperature of the gas, measured in Kelvins.

### What is specific volume and specific area?

Specific volume is defined as the number of cubic meters occupied by one kilogram of matter. It is the ratio of a material’s volume to its mass, which is the same as the reciprocal of its density. In other words, specific volume is inversely proportional to density.

What is the specific volume of oxygen at 40 psia and 80 F?

Thus, the specific volume is 4.5ft3/lbm.

#### What is the volume in chemistry?

Volume is the amount of 3D space a substance or object occupies. Volume is a derived unit, depending on 3 quantities: length, width, and height.

#### What is the formula of volume of rectangle?

The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.

How is nRT calculated?

A mole of any substance has a mass in grams equal to its molecular weight, which can be determined from the periodic table of elements. The ideal gas law can also be written and solved in terms of the number of moles of gas: PV = nRT, where n is number of moles and R is the universal gas constant, R = 8.31 J/mol ⋅ K.

## What is P1 V1 P2 V2?

The relationship for Boyle’s Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.

## What is specific volume example?

For example, if substance A has a specific volume of 0.358 cm3/g and substance B has a specific volume of 0.374 cm3/g, taking the inverse of each value will yield the density. Thus, the density of A is 2.79 g/cm3 and the density of B is 2.67 g/cm3.

What is the specific volume of oxygen?

### How do you calculate specific volume?

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.

### How to calculate volume using specific gravity?

How to Calculate Volume Using Specific Gravity Obtain the specific gravity of the liquid using a refractometer, digital density meter, hydrometer, or a reference chart. Determine the mass of the substance (weigh it using a gram scale) or assign a fictitious amount that is convenient (such… Assign the values in the formula and solve for V (volume). For… See More….

Is specific volume molar volume?

Molar Volume is a mole of a gas that populates a specific volume at an appropriate pressure and temperature. It can be represented by the symbol Vm. Molar Volume is equivalent to the molar mass divided by the mass density. It is represented with the SI unit of cubic meters per mole.

#### How do you calculate volume when given mass?

Therefore, if the density and mass of a substance are known, the volume may be determined by dividing the mass by the density (volume = mass/density). Mass may also be determined by restructuring the formula so that volume multiplied by density equals mass (mass = volume x density).
