One atom of hydrogen reacts with one atom of chlorine forming one molecule of hydrogen chloride (hydrochloric acid). An atom of hydrogen has less mass than one of chlorine so 1 gram of hydrogen contains more hydrogen atoms than one gram of chlorine.
For carbon 0.80 x 100 = 80 grams of carbon; and for hydrogen 0.20 x 100 = 20 grams of hydrogen
Avogadro's number is the number of units per mole. A mole is 6.022x1023 (602,200,000,000,000,000,000,000) units. Because every element has a unique mass, it is primarily useful in chemistry for stoichiometric calculations. Hydrogen for example has a mass of ~1.01 grams per mole, so one gram of atomic hydrogen contains approximately 1 mole of hydrogen atoms, or 6.022x1023 hydrogen atoms. It seems arbitrary until you examine it's applications in practical use. To create a molecule of water you need to combine 2 hydrogen atoms with one oxygen atom, along with a little bit of energy: 2H + O --> H2O If you want to do this efficiently, you can't just throw 2 grams of hydrogen atoms together with 1 gram of oxygen atoms to create 3 grams of water because hydrogen and oxygen have different molecular masses. One oxygen atom is about 16 times heavier than 1 hydrogen atom, so with the above approach you'll only end up with about 1.125 grams of water with about 1.875 grams of hydrogen still floating about. This is where Avogadro's number comes into play. Hydrogen is ~1 gram per mole (1 gram per 6.022x1023 atoms) and Oxygen is ~16 grams mer mole (16 grams per 6.022x1023 atoms). So to create 1 mole of water you need to combine approximately 2x6.022x1023 hydrogen atoms with approximately 6.022x1023 oxygen atoms, light a match, and prepare to get burned.
One gram is equal to one gram.
One gram equals 1000 milligrams.
It is "gram", which may be abbreviated to "g".
75 grams per mole
The gram atomic mass of hydrogen is 1.008.
117(g K) * [1.008(g/mol H) / 39.098(g/mol K)] = 3.02 gram hydrogen
The equation for the reaction between sodium and chlorine is 2 Na + Cl2 -> 2 NaCl. This equation shows that equal numbers of formula units of sodium and chlorine are changed during the reaction. The gram atomic mass of two sodium atoms is 2 [exact] X 22.9898 or45.9796. therefore the specified amount of sodium is 92.0/45.9796 or 2.00 double gram atoms, to the justified number of significant digits. Therefore 2.00 double gram atoms of chlorine are required. The gram atomic mass of chlorine is 35.453, and four times this amount, or 142 grams of chlorine, to the justified number of significant digits, are needed for complete reaction.

no, it doesnt.
The gram molecular mass of H2 is 2g.
Market value is approximately $0.024 per gram.
When sulfur reacts with chlorine to produce disulfur dichloride, the name of the compound corresponds to a chemical formula of S2Cl2, which shows that the same numbers of atoms of each element are needed to form the compound. The gram atomic mass of sulfur is 32.06, and the gram atomic mass of chlorine is 35.453. 200.2 grams of sulfur corresponds to 200.2/32.06 or about 6.2445 gram atoms of sulfur, while 100.3 grams of chlorine corresponds to 100.3/35.453 or about 2.83 gram atoms of chlorine. Therefore, chlorine is the limiting reactant among these amounts of sulfur and chlorine.
From the law of conservation of mass: 58.5 - 23 = 35.5 grams of chlorine required. Interestingly, 23 and 35.5 are approximations to the gram atomic masses of sodium and chlorine respectively.
they yell at them
the cost of oxygen is 2.50 per gram
