100 Liters? I will assume as much.
Molarity = moles of solute/Liters of solution
Molarity = 0.10 mole HCl/100.0 Liters
= 0.001 M HCl
-------------------------now, to find pH
- log(0.001 M HCl)
= 3 pH
-----------------so, your acid is of 3 pH, which is to be expected at the volume od solution

Since the molecular weight of HCl is 36.46g/mole, 1 mole of HCl contains 36.46g. 1 liter of a 0.5M solution will have 18.23g of HCl. 400 ml will have 7.292g of HCl.
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
1.00 m
No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)

It refers to a solution each litre of which contains one tenth of a mole of a particular substance. A mole is a specific number of atoms or molecules - 6.02 x 10 to the power of 23, also known as Avogadro's number. One mole of any substance has a mass equal to its atomic or molecular weight expressed in grams. Thus, one mole of Helium has a mass of 2g; one mole of Sodium Chloride - NaCl - has a mass of 22.98g + 35.45g = 58.43g. It follows that a 0.1 molar solution of NaCl contains 5.843g of NaCl in each litre of solution.
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
It depends on how much solution you have!"1 molar solution" means that 1 litre of the solution contains 1 mole of solute (in this case, Na+ and Cl- ions). Therefore, 1 litre of 1M NaCl will contain 1 mole of sodium chloride. 1 mole is avagadro's number (6.02x1023) of a substance. If you have two litres of solution, obviously, you will have twice this number, for example.Note, though, that there are NO molecules of sodium chloride - sodium chloride is not a molecular substance.
Since the molecular weight of HCl is 36.46g/mole, 1 mole of HCl contains 36.46g. 1 liter of a 0.5M solution will have 18.23g of HCl. 400 ml will have 7.292g of HCl.
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
6 m HCl refers to the concentration of an Hydrochloric Acid solution. It is 6 molal.A 1 molal solution contains one mole of the solute in 1 kg of solvent. In the abovecase the solvent is water.
From the definition of molarity, one liter of the stated solution contains 0.256 mole of sodium bromide. The gram formula weight of sodium bromide is 102.89; therefore, one liter of the solution contains 0.256 X 102.89 or 26.34 grams. 18.7/26.34 = 0.710, the fraction of a liter that contains 18.7 grams of sodium bromide.
