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
There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
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.
There are approximately 12 mEq of sodium in 1g of sodium citrate.
1 gram molybdenum (1 mole Mo/95.94 grams)(6.022 X 1023/1 mole Mo) = 6 X 1021 atoms of molybdenum ========================
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
Yes. One mole (6.022x1023) of hydrogen atoms would have a mass of about 1g.

There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms 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.
In the reaction between 1g of Hydrogen and 19g of Fluorine to form HF, the limiting reactant is Hydrogen. Based on the balanced chemical equation, 1g of Hydrogen will react with 38g of Fluorine to form 2g of HF. In the reaction between 1g of Hydrogen and 80g of Bromine to form HBr, the limiting reactant is Hydrogen. Based on the balanced chemical equation, 1g of Hydrogen will react with 160g of Bromine to form 2g of HBr.
it depends on how much water you have. but the density is 1g/cm^(3) .
Rms= sqrt(((3)(8.314)(273.15k))/(1g/mole)) = 82.54 is the speed of one hydrogen molecule. Assuming stp
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
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.
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.
it is equal because 1g
