# What is the volume of one hydrogen molecule?

## What is the volume of one hydrogen molecule?

Every 1 mole of a gas occupies the same volume at STP which is 22.4 litres. So, we have the value of molar volume for hydrogen $= 22.4l = 22.4 \times {10^{ – 3}}{m^3}$. Now atomic volume can be calculated from the radius of the molecule in the following way.

What is the volume of 3.5 g of hydrogen at STP?

2 g occupies 24 dm3, so scaling up for the volume of hydrogen 3.5 g will have a volume of 3.5/2 x 24 = 42 dm3 (or 42000 cm3)

What is the volume of the gas at STP?

22.41 L/mol
So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.

### How many molecules are in a volume?

The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro’s number and its equal to 6.022*1023 atoms/mole.

What volume would 3.87 1022 molecules of an ideal gas occupy at STP?

Answer: The volume of 3.0 x 1025 molecules Ne at STP is 1100 L .

How do you find the volume of hydrogen?

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 atomic volume of hydrogen?

Solution 2 Volume of one hydrogen atom = 4/3 πr3 (volume of sphere) = 4/3 x 3.14 x (0.5 x 10-10) m3 = 5.23 x 10-31 m3. According to Avagadro’s hypothesis, one mole of hydrogen contains 6.023 x 1023 atoms. Atomic volume of 1 mole of hydrogen atoms = 6.023 x 1023 x 5.23 x 10-31 = 3.15 x 10-7m3.

What is the volume of 1 g of hydrogen at STP?

According to the universal gas constant, 1 mole of ANY gas at STP occupies 22.4 L of space, and since the molar mass of Hydrogen is 1 g, we can say that 1 g of Hydrogen=one mole of Hydrogen, so 1 g of Hydrogen occupies 22.4 L of space.

What volume would it occupy at STP?

22.4 L
At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L.

### What is the volume of hydrogen in various units?

The entered volume of Hydrogen in various units of volume. 1 cubic centimeter of Hydrogen weighs 0.000082 gram [g] 1 cubic inch of Hydrogen weighs 0.000047399 ounce [oz] Hydrogen weighs 0.000082 gram per cubic centimeter or 0.082 kilogram per cubic meter, i.e. density of hydrogen is equal to 0.082 kg/m³; at 0°C (32°F or 273.15K)

What is the volume occupied by 2 moles of an ideal gas?

So, if you are given these values for temperature and pressure, the volume occupied by any number of moles of an ideal gas can be easily derived from knowing that 1 mole occupies 22.4 L. V = n ⋅ V molar For 2 moles of a gas at STP the volume will be 2 moles ⋅ 22.4 L/mol = 44.8 L
