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?
There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
How many atoms are in 1g of hydrogen gas?
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 mEq is in 1g sodium citrate?
There are approximately 12 mEq of sodium in 1g of sodium citrate.
Why is hydrogen gas lighter than air?
[answerer one] the word hydro =water and if water evaporates it transforms into a content of air and hydrogen is a gas which is made up of evaporated liquid this is why hydrogen gas is lighter air [answerer two] Let me take this from a purely chemical point of view. One mole of oxygen gas weighs 32 grams, one mole of nitrogen gas weighs 14.01 grams. At standard temperature and pressure, one mole of gas takes up 22.4 liters of space. Earth's atmosphere is (approximately) 78% Nitrogen, and 22% oxygen, knowing that, one can figure that 22.4 liters of air contains .78 moles of nitrogen, and .22 moles of oxygen, which translates into 7.0 grams of oxygen and 11 grams of nitrogen (approximately). So, the density is 18/22.4 grams per liter. Lets compare that to the density of 22.4 liters of hydrogen. 1 mole of hydrogen weighs 1.01 grams, so the density is 1.01/22.4 grams per liter. So, the density of air is 17.821 times more than the density of helium. Correct me if I'm wrong though, I'm still learning chem. [edit] i was a bit off, but i don't know why. I'm assuming hydrogen to be H-1 isotope, but it could be H-2. Because the atomic weight of hydrogen is lower than the atomic weights of the atomss that typically form "air", namely nitrogen, oxygen, carbon dioxide, and a bunch of other gasses in extremely small concentrations. With lower density, the atoms of hydrogen tend to want to "float" just like liquids behave when different densities are mixed. Hydrogen is #1 on the periodic table of the elements because it has the lowest atomic weight Hello im another person Air weighs 34 tins of baked beans- with nothing inside , this is because of gravity, but if you would weigh it without gravity it would be 17 tins without anything inside so even with gravity hydrogen will be lighter because if hydrogen was 6g- causing gravity, then it would be 3g without gravity dont forget hydrogen is flammable, so it is lighter, but air isnt flammable, so it must be heavier. think of a paper, weigh it about 3g, so burn it about 1g since it all goes together like a family and turns black. By Susana25 also by another person the first bit until hello im another person! Thank you for reading.
What is the molecular weigh of hydrogen peroxide?
The density of a hydrogen peroxide solution will vary slightly based on the exact concentration of hydrogen peroxide. Solutions with higher concentrations will be slightly more dense. However, the density at lower concentrations is around the density of water, 1g/cm3.
How many moles of hydrogen in 1g?
There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
How many grams of each product will form in each reaction if 1g of Hydrogen reacts with 19g of Flourine to forn HF and 1g of Hydrogen reacts with 80g of Bromine to form HBr?
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.
How fast does hydrogen effuse?
Rms= sqrt(((3)(8.314)(273.15k))/(1g/mole)) = 82.54 is the speed of one hydrogen molecule. Assuming stp
How many moles are in 12G hydrogen?
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.
How many atoms are in 1g of hydrogen gas?
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 grams in 10mg?
1g = 1000mg 10mg x 1g/1000mg = 0.01g
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.
