## How do you find the volume of a mole of gas?

**Calculating the volume of a gas**

- Volume = amount in mol × molar volume.
- Volume = 0.25 × 24.
- = 6 dm

## How do you calculate the volume of a gas?

It can be written as: **V = nRT/P**. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature.

## What is the volume of 1 mole of gas in term of volume?

The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02×1023 representative particles) of any gas occupies a volume of **22.4L** (figure below). Figure 10.13. 2: A mole of any gas occupies 22.4L at standard temperature and pressure (0oC and 1atm).

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How do I calculate moles?

So in order to calculate the number of moles of any substance present in the sample, we simply **divide the given weight of the substance by its molar mass**. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

## What is a volume of a gas?

A gas is a collection of molecules that do not cohere strongly enough to form a liquid or a solid. The volume of a gas is, **as long as the molecules fit into it, the volume of the container holding the gas**. In other words, the volume of a gas is NOT a property of the gas directly, but a property of the container.

## What gas occupies 22.4 at STP?

A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm). Figure below illustrates how molar volume can be seen when comparing different gases. Samples of **helium** (He), nitrogen (N_{2}), and methane (CH_{4}) are at STP.
