For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unitis TINY.

Explanation: Know that one mole of any gas at STP takes up 22.4 liters. So 2.4 L of hydrogen is 0.107142857molsH2 . Since H2 reacts with O2 in a 2:1 ratio, to completely react the two you will need half as much oxygen as hydrogen.

Because the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms. For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.

one gram of hydrogen contains one mole of hydrogen as its atomic weight is 1. One mole is 6.02x10^23 atoms. But, hydrogen is diatomic, meaning its atoms are found in pairs so, the amount of molecules would be 3.01x10^23.

That means that 1 kilowatt hour of electricity can split about 270 grams of water and produce about 350 liters of hydrogen and 175 liters of oxygen. It depends on the pressures and concentrations. Assuming standard conditions (1 atmosphere of pressure, 1 mole per liter of H+ ions), then you'd need a voltage of 1.23V.
