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.

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

Explanation: 1 mole of gas would take up 22.4 liters of volume, which is equivalent to 22.4 dm3 of volume. Therefore, multiply answer by 2 (since there are 2 moles), and hence you would get an answer of 44.8dm3 .

## What is the volume of hydrogen in STP?

We know that at STP one mole of any gas occupies 22.4litres . It means that one mole of hydrogen also occupies 22.4litres of volume at STP. So 10moles of hydrogen gas will occupy =22.4×10=224litres of volume at STP.

## What is the volume of 2.0 moles of oxygen gas at STP?

Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

## What is the mass of 2 moles of hydrogen?

So two moles is 64 g. A mole is useful because it’s the number of atoms needed to convert atomic mass units into grams. So a mole of carbon is 12 grams. A mole of helium is 4 grams.

## What gas occupies 22.4 at STP?

Oxygen gas is made up of diatomic molecules (O2). Therefore 22.4 L of oxygen gas at STP contains 1 mole of O2 molecules.

## What is the volume of 0.5 moles of gas at STP?

0.5 moles⋅22.4 L/mol=11.2 L , and so on.

## What volume does 1 mole of hydrogen occupy at STP?

One mole of any gas at STP will occupy 22.4 liters of volume.

## What is the volume of 2.5 moles of H2?

The volume is 28.8 L .

## What is the volume of 3 moles of hydrogen gas at STP?

Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L . Due to the new conditions of STP , the new molar volume using the ideal gas equation (PV=nRT) comes out as 22.7 L . 3mol ⋅22.7 Lmol =68.1 L .

## What is the mass of 2 mole of oxygen gas at STP?

Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

## What is the volume of 3.5 moles of O 2 gas?

The answer is 39.2L . The gas laws tell us that all ideal gasses behave identically under the same conditions. At STP, the molar volume of any ideal gas is equal to Vmolar=22.4L , which means that 1 mole of any gas at STP will occupy exactly 22.4L .

## What is the volume of 0.50 moles of oxygen gas O2 at STP?

400⋅mL .

## Is the molar mass of hydrogen 1 or 2?

However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.

## How many moles of oxygen react with 2 moles of hydrogen?

From the above reaction, 2 moles of hydrogen will react with 1 mole of oxygen. Hence, 1 mole of oxygen is required.

## Is H2 one or two moles?

As hydrogen gas naturally occurs in a diatomic state, it is true that there is only one mole of naturally-occurring elemental hydrogen in answer one, but one mole of H2 is formed from 2 moles of H.
