## What is the volume of 3 moles of gas?

So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas.

## What is the volume of helium gas?

Assuming that helium behaves as an ideal gas, we know that a mole of ideal gas occupies 22.4 litres at STP. The atomic weight of helium is 4 g/mol, so 6 g is 1.5 moles. The volume occupied at STP, therefore, is 22.4 x 1.5 = 33.6 litres.

## What is molar volume of a gas What will be the volume of 3 moles of o2 gas at STP?

3 moles of oxygen at STP will occupy a volume of 3×22. 4=67.

## What is the volume in Litres at STP of 3 moles of h2s gas?

Explanation: Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L .

## What is the volume of 3 moles of n2 gas at STP?

Volume at STP:

Assuming the given gas is ideal, it’s usually one mole of gas that corresponds to or occupies the total volume of 22.4 liters when the pressure is one atm, and the temperature is 298 K that is STP.

## What is the volume of 1 kg helium?

The volume of 1 kg of helium in a piston-cylinder device is initially 5 m^3. Now helium is compressed to 2 m^3 while its pressure is maintained constant at 130 kPa.

## What is the formula of volume?

## What is the volume of gas at NTP?

We can define molar gas volume as one mole of gas at a particular temperature and pressure contains the fixed volume. The standard temperature is 0∘C or 273K. The standard pressure is 1atm or 760mmHg. The volume occupied by 0.1 mole of gas at NTP is 2.24Litres.
