How many moles of HCl are represented by 1.0x1019 HCl molecules?
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.
How many molecules are there in 3.46 kg hydrochloric acid?
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.
How many moles of HCl and needed to react 2.4 moles of Al?
Al+HCl===> AlCl3+H2 Is the reaction. You need &.2 moles of HCl.
How many moles are present in a sample of HCl with a mass of 3.65?
0.1mol
How many moles of zn are consumed when 1.60 x 1024 molecules of hcl react completely in the following equation zn plus 2hcl equals zncl2 plus h2?
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.
How many moles HCl in 8.3 g HCl?
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles HCl ------------------------
How many moles of NaCl are formed from the reaction between 1.4 moles of HCl and 2.8 moles NaOH?
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.
What is the mass of of 1.6 x 1023 molecules of HCL?
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.
How many moles of solute are in 50 mL of a 12 M HCl solution?
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).
How many moles are in 2 grams of HCL?
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.
How many moles of HCl are present in 0.250 L of 0.400 M HCl?
Molarity = moles of solute/liters of solution, so... 0.400M HCl (X mols HCl/0.250L ) = 0.100 moles HCl
How many moles of HCl are on 10 grams of substance?
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.
