hydrogen chloride = H+1, Cl-1 = HCl
H = 1.008
Cl = 35.453
HCl = 36.458 g/mol
21.1 g x 1 mol HCl/36.458g = .579 mol HCl
The ions of hydrogen chloride balance out so the formula is HCl. You add the atomic weights of the individual elements to get a grams/mole for the molecule HCl. You take the information that was given, 21.1g of HCl, and multiply it by the fact that 1 mole of HCl is 36.458g. Grams cross out and you're left with 21.1 x 1 mol / 36.458 = .579 mol. This is how many moles are in 21.1g of HCl.
What else can I help you with?
How many chlorine atoms are present for every atom in a hydrogen chloride molecule?
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
How many mols of NaCl are present in 1 liter of a 0.1M solution of sodium chloride?
There would be 0.1 moles of NaCl present in 1 liter of a 0.1M solution of sodium chloride. This is based on the definition of molarity which is moles of solute per liter of solution.
How many moles of hydrogen chloride can be produced from 0.490 grams of Hydrogen and 50.0 grams of chlorine?
The atomic mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
How many moles of sodium chloride solute are in 155 grams of an 85.5 percent by mass solution?
To find the moles of sodium chloride solute in 155 grams of an 85.5% solution, first calculate the mass of sodium chloride present in the solution (mass percent x mass of solution). Then, convert the mass of sodium chloride to moles using its molar mass (58.44 g/mol). This will give you the number of moles of sodium chloride solute in the solution.
How many moles of hydrogen chloride are needed to form 1 mole of lithium?
Lithium can never be formed from hydrogen chloride in a chemical reaction, because lithium, hydrogen, and chlorine are all distinct elements, none of which can be converted any others by chemical means.

How many moles of CC14 are present in 56g?
This is carbon tetra chloride. there are 0.3636 moles in this mass.
How many molecules of hydrogen chloride would there be in 100 grams of this gas?
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.
How many mols of NaCl are present in 1 liter of a 0.1M solution of sodium chloride?
There would be 0.1 moles of NaCl present in 1 liter of a 0.1M solution of sodium chloride. This is based on the definition of molarity which is moles of solute per liter of solution.
How many moles of hydrogen are present in 3 moles of methane?
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
How many moles of hydrogen atoms are present in 2 moles of benzene?
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
How many moles of hydrogen chloride acid are in 3.45g?
To find the number of moles of hydrogen chloride in 3.45g, you need to divide the mass by the molar mass of HCl. The molar mass of HCl is approximately 36.46 g/mol. So, 3.45g / 36.46 g/mol = 0.0945 moles.
How many grams of hydrogen chloride can be produced from 0.490 g of hydrogen and 50.0 g of chlorine?
