27,000 million, million, million molecules. Answer

Avogadro'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

What happens to the number of molecules of the gas when it is compressed?

When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.


Gas pressure is affected by?

Gas pressure is affected by factors such as temperature, volume, and the number of gas molecules present. Increasing the temperature or decreasing the volume of a gas will result in an increase in pressure, while increasing the number of gas molecules will also increase the pressure.


What are examples of Avogadro's law?

If you have two containers of gas at the same temperature and pressure, the container with twice the volume will contain twice the number of gas molecules. If you change the volume of a gas sample while keeping the temperature and pressure constant, the number of gas molecules will adjust in proportion to the volume change according to Avogadro's law.


A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?

If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.


When a gas is compressed in a cylinder what does the distance between the gas molecules do?

The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.

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.


Will decreasing the number of gas molecules increase the volume of a gas?

Decreasing the number of gas molecules typically decreases the volume of the gas, assuming pressure and temperature remain constant. This is because there are fewer molecules colliding with the container walls, reducing the pressure and allowing the gas to occupy a larger volume to maintain equilibrium.


What effect does a decrease in volume have on the number of gas molecules?

Three variables that effect volume (V) of gas are pressure (P), temperature (T), and how many moles (n) of gas are present in a system. Decreasing any of these variables correspond to gas volume reductions. These can be related by the Ideal Gas Law equation of PV = nRT. R is the Ideal Gas constant of .0821 Liters/ATM*moles*Kelvin.


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.


How does pressure and number of gas molecules relate?

Pressure and the number of gas molecules are directly related in accordance with the ideal gas law. As the number of gas molecules increases, the pressure also increases, assuming volume and temperature are constant. This relationship is described by the equation PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature.


Does gas have mass or volume?

Gas has mass, but it does not have a definite volume because it conforms to the shape and size of its container. The mass of a gas is determined by the number of gas molecules present.


What happens to the number of molecules of the gas when it is compressed?

When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.

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.
