How can I calculate the molar volume of hydrogen gas?

The actual molar volume of hydrogen can be exactly calculated from the experimental density of that gas, that is 0,0899 g/L at 0 °C (1 atm ) and 0.0837 g/L at 20 °C (1 atm), knowing that one mole of dihydrogen (#H_2#) amounts to 2,0159 g/mol.

How many moles are present in hydrogen gas?

The answer is 1.00794. We assume you are converting between grams Hydrogen and mole. The SI base unit for amount of substance is the mole. 1 grams Hydrogen is equal to 0.992122546977 mole. Note that rounding errors may occur, so always check the results.

Is hydrogen gas an ideal gas?

Like a helium atom, a hydrogen molecule also has two electrons, and its intermolecular forces are small. The electrical charge is spread across two atoms. The ideal gas composed of more than one atom is hydrogen gas. As gas molecules get larger, they behave less like ideal gases.

What is the average value of the molar volume of hydrogen?

These values of true molar volume of hydrogen are very close to the ideal gas values of 22,41 L/mol and 24,0 L/mol at 0 °C and 20 °C, respectively, thus confirming that hydrogen gas behaves almost ideally.
