What is the mass of 2 moles of hydrogen gas?

Answer: 1 mole of hydrogen gas weighs 2 gram so 2 moles weigh 4 grams mate hope this helps.

What is the mass of 2 moles of H?

Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

How many grams are in 2 moles of hydrogen?

Mass of 2 moles of hydrogen molecule = 2 × 2 = 4 g.

What is the mass of moles of hydrogen gas?

The molar mass of hydrogen gas is 2.016 grams per mole.

What is the mass of a hydrogen molecule?

A hydrogen, nitrogen, or oxygen molecule, consists of two identical atoms of each of those respective elements. Therefore, a hydrogen molecule’s mass is 2 amu, oxygen is 32 amu and nitrogen is 28 amu. Now let’s talk about what is meant by a MOLE of a substance…also refered to as a gram-mole.
