To determine the number of molecules in 100 grams of hydrogen chloride gas, you need to first calculate the number of moles present using its molar mass. The molar mass of HCl is about 36.5 g/mol. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.

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.
How many hydrogen molecules are needed to produce 525 grams of ammonia?
To produce 525 grams of ammonia (NH3), you would need 25 moles of ammonia. Since the balanced chemical equation for the reaction between hydrogen and nitrogen to form ammonia is 3H2 + N2 -> 2NH3, you would need 75 moles of hydrogen molecules (H2) to produce 525 grams of ammonia. This is equivalent to 4,500 molecules of hydrogen.
What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
17.031 grams of ammonia has more atoms because ammonia has a larger molecular weight than hydrogen chloride. Ammonia has a molecular weight of 17 grams/mole and hydrogen chloride has a molecular weight of 36.5 grams/mole, so the same mass of ammonia would contain more moles and therefore more atoms.
What mass of hydrogen chloride is formed when 1 mole of hydrogen reacts with 1 mile of chlorine?
1 mole of hydrogen reacts with 1 mole of chlorine to form 2 moles of hydrogen chloride. The molar mass of hydrogen chloride is 36.46 g/mol. Therefore, 2 moles of hydrogen chloride would have a mass of 72.92 g.
The molecular formula for hydrogen sulfide is H2S. What does the formula indicate about the composition of a 1.0-gram sample of hydrogen sulfide?
The molecular formula H2S indicates that in every molecule of hydrogen sulfide, there are 2 atoms of hydrogen and 1 atom of sulfur. Therefore, in a 1.0-gram sample of hydrogen sulfide, there would be 0.67 grams of hydrogen (2/3 of 1.0 grams) and 0.33 grams of sulfur (1/3 of 1.0 grams).

How many molecules of sodium chloride are in 29.22 grams of NaCl?
There are approximately 0.5 moles of NaCl in 29.22 grams. This would be 3.01 x 10^23 molecules of NaCl.
If 4.0 g of hydrogen react with chlorine to produce 146 g of hydrogen chloride how many grams of chlorine reacted?
The balanced chemical equation for the reaction between hydrogen and chlorine is: H2 + Cl2 -> 2HCl. From the equation, we see that 1 molecule of Cl2 reacts with 1 molecule of H2 to produce 2 molecules of HCl. Thus, 4.0 g of hydrogen would react with 118.5 g of chlorine (146 g of hydrogen chloride - 27.5 g of hydrogen).
What are the chemical symbols for iron chloride plus hydrogen?
The chemical symbol for iron chloride is FeCl3 and the chemical symbol for hydrogen is H2. Therefore, the combination of iron chloride with hydrogen would result in the reaction FeCl3 + H2.
If one adds 5 grams of sodium chloride and 5 grams of calcium chloride to water at what temperature would you expect the solution of sodium chloride and calcium chloride to boil?
You get salt at the bottom of the pan!

How many hydrogen molecules and oxygen molecules would you need to start with to make 10 water molecules?
20 hydrogen 10 oxygen
Which acid and metal would you use to make zinc chloride?
Zinc (Zn) and hydrogen chloride HCl)
How many atoms are in 1.008 grams of hydrogen?
hydrogen is H2, with a molecuar weight of 2.016. In 1.008 grams of H2 there are 3.011 X 10 raised to power 23 (approx) 2.011 X 1023 molecules or 6.022 X 1023 atoms. Ovviously you can go straight to the answer as the weight is the atomic mass in grams.
