Trick question. Hydrogen is a diatomic molecule; it travels around with a buddy as H2 and not as a single atom. This is generally true of all gases except the inert gases. By definition, a mole of anything has 6.022 x 1023 "units" of that stuff. (That's Avogadro's number.) The "stuff" is the atoms or the molecules of that "stuff" and it can be thought of in terms of the "reaction units" of that stuff. We do not have H2 + O = H2O. We have 2H2 + O2 = 2H2O because oxygen is diatomic like hydrogen. The "reaction units" of hydrogen and oxygen are H2 and O2 respectively. Now the answer will appear. A mole of hydrogen is 6.022 x 1023 units of hydrogen which will be 6.022 x 1023 molecules of hydrogen which will be (6.022 x 1023 times 2) atoms of hydrogen which will be 1.204 x 1024 atoms of hydrogen.

What mass of hydrogen chloride is formed when 1 mole of hydrogen reacts with 1 mole of Chlorine?

When 1 mole of hydrogen reacts with 1 mole of chlorine, 2 moles of hydrogen chloride are formed. The molar mass of hydrogen chloride is 36.46 g/mol. Therefore, 2 moles of hydrogen chloride would have a mass of 72.92 grams.


What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?

Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.

How many hydrogen atoms are in 871 grams of water?

Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================


How many GRAMS of hydrogen are present in 2.08 moles of water?

In 1 mole of water (H2O), there are 2 moles of hydrogen (H). This means that in 2.08 moles of water, there are 2.08 x 2 = 4.16 moles of hydrogen. To convert moles to grams, we use the molar mass of hydrogen: 4.16 moles x 1.01 g/mol = 4.22 grams of hydrogen.


How many grams of hydrogen are in 25.0g of water?

25x(2/18)=2.78g of hydrogen 25x(16/18)=22.22g of oxygen


What is the atomic mass of chloride?

How many gram of chlorine are need to combined with 23gram of sodium to make 58.5gram of sodium chloride?

You would need 35.5 grams of chlorine to combine with 23 grams of sodium to make 58.5 grams of sodium chloride. This is based on the molar mass of sodium chloride, where one mole of sodium chloride is composed of one mole of sodium (23 grams) and one mole of chlorine (35.5 grams).
