# What is the volume of 1 mole of hydrogen gas?

Contents

According to Avogadro’s law, the volume of one mole of any gas at Standard Temperature and Pressure (STP = 273 K and 1 atm) is 22.4 L. Two important Gas Laws are required in order to convert the experimentally determined volume of hydrogen gas to that at STP. 1.

## What is volume of 1 mole of hydrogen?

Molar volume, or volume of one mole of gas , depends on pressure and temperature, and is 22.4 liters – at 0 °C (273.15 K) and 1 atm (101325 Pa), or STP (Standard Temperature and Pressure), for every gas which behaves similarly to an ideal gas.

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

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).

## How do you calculate volume of hydrogen gas?

1. Step 1 – Calculate the amount of sodium. Amount in mol = Amount in mol = …
2. Step 2 – Find the amount of hydrogen. From the balanced equation , the mole ratio Na:H 2 is 2:1. Therefore 0.20 mol of Na produces = 0.10 mol of H 2
3. Step 3 – Calculate the volume of hydrogen. Volume = amount in mol × molar volume. Volume = 0.10 × 24.

## What is the molar volume of hydrogen gas at room temperature?

Molar volume of the ideal hydrogen gas at room temperature (Volume/moles), expressed as L/mol at X degrees C and a pressure of 1 atmosphere = 22.4 L/mole * …

## What is the volume of oxygen?

We now know that the volume of 2.155 × 10​​-3 moles of oxygen is about 52.88 cm3. Use this information to calculate the volume of one mole of oxygen. (Your answer may not be exactly this figure, but should be close to it.) At STP, all gases have the same molar volume, which is about 24,000 cm3.

## What is mole in chemistry?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## How many liters of gas are needed for 1 mol?

As long as the gas is ideal, 1 mole = 22.4L.

## Is Mol and volume the same?

The volume of 1 mole of any gas is called its molar volume and is equal to 22.4 L at standard temperature and pressure. Molar volume allows conversions to be made between moles and volume of gases at STP.

## How do I find the volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

## What is r in PV nRT?

PV = nRT. The factor “R” in the ideal gas law equation is known as the “gas constant”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.

## How do you convert volume to volume at STP?

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. Record the molar gas constant “R”.

## What is the total volume of hydrogen gas and oxygen gas?

The volume of a mole of gas at standard temperature and pressure is 22.4 liters. So the amount of H2 will be 22.4 L and the volume of O2 will be 1/2 x 22.4 = 11.2 L.

## What is the volume of 2 moles of hydrogen gas at STP?

At STP, one mole of any gas occupies 22.4 litres of volume. One mole of a gas is given by the Avogadro’s number i.e. NA and it is given as 6.023×1023. According to this, one mole of hydrogen gas at STP will occupy 22.4 L of volume. Therefore, 2 moles of hydrogen gas will occupy a volume twice of 22.4 L i.e. 44.8 L.

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

Molar volume of gases

1. volume = 0.5 × 24 = 12 dm 3
2. Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
3. The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known:
4. number of moles = volume of gas at rtp ÷ 24.
