Amount of hydrogen gas = 1.0/2.0 = 0.50mol
In each molecule of hydrogen gas there are two hydrogen atoms.
1 mol of H2 contains 6.02 x 1023 molecules (avogadro constant).
Number of H atoms = 2 x 0.50 x 6.02 x 1023 = 6.02 x 1023

How many electrons are there in 1g of hydrogen gas?
The gram atomic mass of hydrogen is close to 1, so that 1 g of the gas contains one mole of hydrogen atoms. Each atom contains 1 electron, so that the stated amount of gas contains Avogadro's Number of electrons, 6 X 1023 to the justified number of significant digits.
How many moles of hydrogen in 1g?
About 1 mole
How many atom in 1g of molybdenum?
1 gram molybdenum (1 mole Mo/95.94 grams)(6.022 X 1023/1 mole Mo) = 6 X 1021 atoms of molybdenum ========================
How many mEq is in 1g sodium citrate?

How many atoms are in one gram of calcium?
To work this out you need to know the atomic weight of calcium and Avogadros number, which is the number of atoms in a gram atom. Calcium has an atomic weight of 40.078. Therefore a gram ato is 40.078 grams which contains 6.02214129(27)×1023 atoms. 1g of calcium contains 6.02214129(27)×1023 / 40.078 1.502 X 1022
Is there such thing as 6.0221023 atoms equal to 1g?
Yes. One mole (6.022x1023) of hydrogen atoms would have a mass of about 1g.
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
If 1g of hydrogen contains 602000000000000000000000 atoms of hydrogen what is mass of 1 hydro gon atom?
1
How many electrons are there in 1g of hydrogen gas?
The gram atomic mass of hydrogen is close to 1, so that 1 g of the gas contains one mole of hydrogen atoms. Each atom contains 1 electron, so that the stated amount of gas contains Avogadro's Number of electrons, 6 X 1023 to the justified number of significant digits.
How many moles of hydrogen in 1g?
About 1 mole
1 pound of hydrogen is How many cubic feet?
One pound = 0.453592kg. One Mole of H = 1g 0.453592kg of H = 453.592 mole of H According to the ideal gas law, one mole of gas will occupy 22.4 liters as stp. One pound of H will occupy 10,160.2608 liters, or 358.806 cubic feet. Be careful. Most applications of this calculation will deal with hydrogen gas, which has two hydrogen atoms per molecule at standard temperature and pressure. In such cases, divide the volume calculated above by two.
What is the number of hydrogen atoms in 2 moles of sulfur hexahydride?
The answer is 72,24.1023 atoms of H. Hydrogen - 1 mole = 1g (atomic mass '1'). 1 (hydrogen atomic number) x 2 (specified moles) x 6 (hydrogen atoms in SH6) x (6.02 x 10^23) (avogadro's number). Avogadro's number is used in working out molarity, using the above equation. But I suppose that you think to SF6, sulfur hexafluoride.
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
How many moles are present in 1g of MgO?
2 Mg(OH)2 have 10 atoms.
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
What are three facts about atoms?
They all contain electrons, protons, and neutrons. They are always neutral, or they would be Ions (I-ons) They have quarks that make up all or the protons and neutrons and electrons there are 623 billion atoms in 1g of hydrogen and 4g of helium and 7g of lithium ect 623 billion=1 mol
How many 25cg is equal to 1g?
