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 the molar volume?
At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.
How do you find the specific gravity of a mixture of gases?
Gas specific gravity is defined as the ratio of the density of the gas to the density of air at 1 atm pressure at 60°F (standard conditions). If ideal gas law behavior is assumed, gas specific gravity is the molecular weight of the gas divided by the molecular weight of air.
How do you calculate volume with mass and density?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).
How to find the mass of a gas mixture?
The mass of a gas mixture can be expressed as: mm = m1 + m2 + .. + mn (2) where. m1 + m2 + .. + mn = the mass of each gas component in the mixture.
What is the most common example of gas mixtures?
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.

How to determine the specific heat capacity of a mixture?
Correspondingly, the first step to determining the specific heat capacity of a mixture is to link each component in the mixture through the first law of thermodynamics. Markedly, the first law of thermodynamics states that energy cannot be created, or destroyed.
How to calculate specific heat capacity?
Step 1. Select the number of materials in the mixture you would like to calculate. Select either “ Mass ” or “ Volume ” from the drop-down. Select your units from the second drop-down . Click “Continue” to move onto the next step. Step 1 – The initial setup for calculating specific heat capacity of a mixture.
How does sensible heat differ from latent heat?
Latent heat stores most energy in the form of a phase change, whereas sensible heat stores energy through a temperature change. As a result, this energy is therefore influenced by specific heat capacity. During this study, it was found that sensible heat energy storage increased, when PCMs were mixed with asphalt.
Why do people add salt to water?
A common myth most people believe to be true, is the act of adding salt to water, in hopes of shortening the mixture’s boiling time. The Rule of Mixtures Calculator can be used to demonstrate how the addition of salt would affect the specific heat capacity, and therefore boiling point of the solution.

Specific Volume Formulas
- There are three common formulas used to calculate specific volume (ν): 1. ν = V / mwhere V is volume and m is mass 2. ν = 1 /ρ = ρ-1where ρ is density 3. ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity The second equation usually is applied to liquids and solids because they are relativ...
Table of Common Specific Volume Values
- Engineers and scientists typically refer to tables of specific volume values. These representative values are for standard temperature and pressure (STP), which is a temperature of 0 °C (273.15 K, 32 °F) and pressure of 1 atm. Substances marked with an asterisk (*) are not at STP. Since materials aren't always under standard conditions, there are also tables for materials that list sp…
Uses of Specific Volume
- Specific volume is most often used in engineering and in thermodynamics calculations for physics and chemistry. It is used to make predictions about the behavior of gases when conditions change. Consider an airtight chamber containing a set number of molecules: 1. If the chamber expands while the number of molecules remains constant, the gas density decreases a…
Specific Volume and Specific Gravity
- If the specific volumes of two substances are known, this information may be used to calculate and compare their densities. Comparing density yields specific gravityvalues. One application of specific gravity is to predict whether a substance will float or sink when placed on another substance. For example, if substance A has a specific volume of 0.358 cm3/g and substance B …
