Determine the volume of hexane that contains 5.33 X 10 22 molecules of hexane.?
To determine the volume of hexane containing 5.33 x 10^22 molecules, first calculate the moles of hexane using Avogadro's number (6.022 x 10^23 molecules per mole). Then, use the density of hexane (0.659 g/mL) to calculate the volume. Finally, convert the volume from milliliters to liters if needed.
When a liquid is heated how does its volume change?
When a liquid is heated, its volume generally expands and increases, causing the molecules to move further apart. This expansion is due to the increase in the kinetic energy of the molecules, which leads to weaker intermolecular forces and greater separation between the molecules.
If you put 4 milliliters of salt into 50 milliliters of water why does the volume not increase by the amount you put in?
It's because the salt disolves into the water instead of adding more volume to it. The salt molecules are "taken apart" (dissociated) by the water molecules, and they are converted into Na+ and Cl- ions. These ions can fit "between" the water molecules, and can do so without increasing the volume of the solution. More salt can be added without increasing the volume, too. That is until saturation is reached, and then no more salt will go into solution. Adding additional salt beyond this point will increase the volume.
When you add sugar to tea the volume of the tea does not appear to change. Explain this observation?
When sugar dissolves in tea, it forms a solution and takes up space between the water molecules without significantly altering the volume of the tea. The sugar molecules integrate themselves within the spaces between the water molecules, which allows the tea to maintain its volume.
What is the number of molecules in a unit volume of a gas?
27,000 million, million, million molecules. AnswerAvogadro's Number tells us that 22.4 liters (1 mole) of any gas at standard temperatue and pressure contains 6.022 x 1023 molecules. 1 liter then contains 1/22.4 of this amount or 268x 1020 molecules
Do gas molecules have definite shape and volumes?
This is more theoretical than anything, as nobody has actually seen one.
Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
Why a gas would have higher entropy than a liquid?
Gas molecules have fewer constraints on their location, than liquid molecules. Molecules in a liquid have to remain in contact with the other molecules of the liquid, and are limited to a specific volume. Gas molecules can go anywhere, they are not connected to anything. So with more possible locations, gas molecules represent a state of higher entropy or disorder.
Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
What has mass volume and is made of atoms?
molecules
Does a paperweright have volume?
Yes. Everything has volume. Anything with 3 dimensions does, i.e. anything that exists
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
How is density related to the packing of molecules?
molecules are packed together and make volume density.
What is the volumes of gas molecules relative to the total gas volume?
The volume of gas molecules is negligible compared to the total gas volume. Gas molecules themselves occupy a very small fraction of the total volume of the gas, with the majority of the volume being empty space between the molecules.
What is anything that has made and takes up space?
Matter is anything that has mass and volume, meaning it takes up space. This includes all physical substances in the universe, such as atoms, molecules, and larger objects like planets and stars.
What is anything that does has mass and volume?
matter is what has volume and mass also occupies space. It exists in three state namely: solid- has mass, volume and shape, Liquid- has volume and mass, and Gas- has volume and mass too.
When density increases the number of molecules in a volume increases decreases varies or stays the same?
When density increases, the number of molecules in a volume stays the same. Density is defined as mass per unit volume, so as the mass increases, there needs to be a proportional increase in the number of molecules to maintain the density.
