There are idealand non-ideal mixtures. In the second case the intermolecular forces between the different molecules of the mixture are less (Positive deviations from Raoult's Law) or more (Negative deviations from Raoult's Law) strong than they are in the pure liquids.
This difference in the intermolecular forces causes a expansion (less strong) or retraction (more strong) of the volume after the mixing, this is the cause of the excess molar volume.
The excess molar volumes VE can be calculated by using measured experimental densities and correlated by the Redlich−Kister type equation.

Why flat side up reducer is used at pump suction?
To compensate high suction volume during startup of he pump. the reducer area below the pipeline at the suction stores excess volume of fluid.
What is the clearance volume of petrol engine?
The volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
Which direction do you turn the screw on the water pressure regulator to increase volume?
Screw in clockwise to increase pressure, has nothing to do with volume. Volume can only be increased by upsizing the pipe diameters. That's why it is called a pressure reg., not a volume reg.
How is a volume knob a resistor?
It is a type of resistor called a potentiometer, which is a resistor with a movable center tap. The full volume signal is applied across the full resistor and the variable volume signal is taken off the movable center tap.
What is mean by CV in thermodynamics?
CV Stands for Control Volume Only in Thermodynamics and it is a fixed region in a open systems. The region of space enclosed by The open system boundaries is called Control Volume.
How do you measure 10 fold molar excess?
To measure a 10-fold molar excess of a substance, you would need to ensure that there is a concentration of that substance that is 10 times higher than the other reactant or product in the reaction. This can be achieved by calculating the molar ratio of the two substances and adjusting the volume or concentration accordingly. It is important to make sure that the excess does not lead to undesired side reactions or waste of resources.
How do you calculate the molar volume of a substance?
To calculate the molar volume of a substance, you divide the volume of the substance by the number of moles present. This can be done using the formula: Molar Volume Volume / Number of Moles.
What is it called when a mole of gas occupies 22.4 liters?
Standard molar volume of the substance.
If given number of moles volume density and molar volume how do you find the molar mass?
Molar mass is the sum of all of its elements' average atomic mass in grams. Such as: NH4 would be calculated by adding nitrogen's aam (14.007) and hydrogen's aam multiplied by four (1.0079 x 4 = 4.0316). Therefore, ammonium's molar mass would be (14.007+4.0316) 18.039. Rounded to sig figs.
What does molar volume mean for a gas?
Molar gas volume is the volume of ONE moel of gas. It only depends on the pressure and temperature, not on the kind of gas. Molar volume at standard temperature and standard pressure is always 22,4 Litres (for any gas)
How do you determine molar volume?
Penis
What happens to volume when moles are halved?
The volume is 50 %; the molar volume is 22,414 L.
What is difference between partial molar volume and specific volume?
Partial molar volume is the volume occupied by one mole of a component in a mixture at constant temperature and pressure, while specific volume is the volume occupied by one unit mass of a substance. Partial molar volume takes into account the presence of other components in the mixture, while specific volume is unique to a single substance regardless of its surroundings.
Molar volume of liquid is greater than molar volume of gas. why?
The molar volume of a liquid is greater than that of a gas because in a liquid, the particles are closer together and have stronger intermolecular forces holding them in place, resulting in a higher density compared to a gas where particles are more spread out and have weak intermolecular forces. This leads to a smaller volume per mole for gases compared to liquids.
What is the relationship between water molar volume and its physical properties?
The molar volume of water is the amount of space one mole of water occupies at a specific temperature and pressure. The physical properties of water, such as density, boiling point, and specific heat capacity, are influenced by its molar volume. As the molar volume of water changes, its physical properties also change accordingly.
What is molar volume of hydrogen at stp?
The molar volume of hydrogen gas at STP (Standard Temperature and Pressure) is 22.4 liters per mole.
Why excluded volume is less than the molar volume in van der waal's equation?
In the van der Waals equation, the excluded volume is considered to be less than the molar volume because it accounts for the volume occupied by gas molecules themselves, which reduces the available space for the gas particles to move around freely. This reduced effective volume results in a difference between the molar volume and the true volume of the gas.
