507 x (6.022 x 10^23)
To convert from number of molecules to moles, we use Avogadro's number: 1 mole = 6.022x10^23 molecules. Therefore, 1.0x10^19 HCl molecules is equal to 1.66x10^-5 moles of HCl.
Mass of HCL given=3.46kgs = 3460 grams of HCL No. of moles of HCL=Mass of HCL provided/Atomic mass of HCL=3460/36.5=94.8 moles no. of molecules=no. of moles x Avogadro number=94.8 x 6.022 x 1023 =57 x 1024 molecules.
Al+HCl===> AlCl3+H2 Is the reaction. You need &.2 moles of HCl.
0.1mol
1 mole of Zn reacts with 2 moles of HCl. Thus, 1.60 x 10^24 molecules of HCl is equivalent to 0.8 x 10^24 moles of HCl. Since the mole ratio is 1:1 between Zn and HCl, 0.8 x 10^24 moles of Zn are consumed in the reaction.
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles HCl ------------------------
The balanced chemical equation for the reaction between HCl and NaOH is: HCl + NaOH -> NaCl + H2O Since the stoichiometry of the reaction is 1:1 for NaCl and HCl, if 1.4 moles of HCl react, then 1.4 moles of NaCl will be formed.
To find the number of moles of solute in the solution, first, calculate the amount of HCl in grams using the formula: moles = molarity x volume (in liters). Then, convert the grams of HCl to moles by dividing by the molar mass of HCl (36.46 g/mol).
To find the mass of 1.6 x 10^23 molecules of HCl, we first need to determine the number of moles. Since Avogadro's number is approximately 6.022 x 10^23 molecules per mole, we have: 1.6 x 10^23 molecules ÷ 6.022 x 10^23 molecules/mole ≈ 0.266 moles of HCl. The molar mass of HCl is about 36.46 g/mol, so the mass is: 0.266 moles x 36.46 g/mol ≈ 9.7 grams.
To find the number of moles in 2 grams of HCl, you need to divide the mass by the molar mass of HCl. The molar mass of HCl is approximately 36.46 g/mol. Therefore, 2 grams of HCl is equal to 2/36.46 = 0.055 moles.
Molarity = moles of solute/liters of solution, so... 0.400M HCl (X mols HCl/0.250L ) = 0.100 moles HCl
To find the number of moles, you need to divide the given mass (10 grams) by the molar mass of HCl (36.46 g/mol). This will give you approximately 0.274 moles of HCl.
