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.
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 of atoms are present in 154 g of HCl?
Divide by molar mass and check the units(italicalized):0.140 (g HCl) / 36.45 (g.mol-1HCl) = 3.84*10-3 mol HCl
How many hydrogen atoms in 2 moles of hydrochloric acid?
In 2 moles of hydrochloric acid (HCl), there are 2 moles of hydrogen atoms. Since each molecule of HCl contains one hydrogen atom, multiplying the moles of HCl by Avogadro's number (6.022 x 10^23) gives the number of hydrogen atoms. Therefore, there are 1.204 x 10^24 hydrogen atoms in 2 moles of HCl.
How many moles of HCL in one liter of stomach fluid?
pH of stomach fluid = 2 [H+] = 1 x 10 to the power -pH = 1 x 10 to the power -2 = 1/10 squared = 0.01 M

How many molecules of hcl are in 507 moles?
507 x (6.022 x 10^23)
How many teaspoons in 50ml of blood?
There are approximately 10 teaspoons in 50ml of blood.

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 are present in a 0.0250 L solution?
1. First, remember definition of M (moles), M = moles of species / L. 0.33 M = 0.33 moles HCl / L 2. Then, multiple your volume by the molar concentration: 0.33 moles HCl / L x 0.70 L = 0.231 moles HCl or you can say n=CONCENTRATION multiply by VOLUME(HCl) which gives 2310 mol HCl It's helpful to carry the units with your calculations. That way you can check that numerators and denominators cancel to give you the units of your answer.
How much caustic soda is required to neutralize a 25ml HCl solution at pH 3?
One step at a time.1/103 = 0.001 M HCl, so.....Molarity = moles of solute/Liters of solution ( 25 ml = 0.025 Liters )0.001 M HCl = X moles HCl/0.025 Liters= 2.5 X 10 - 5 moles HCl========================now, balanced eqiationNaOH + HCl --> NaCl + H2O ( all one to one )( now drive reaction towards mass NaOH )2.5 X 10 - 5 moles HCl (1 moles NaOH/1 mole HCl)(39.998 grams/1 mole NaOH)= 10 -4 grams caustic soda needed==========================
How many moles of hcl are needed to react with 0.35 g of NAHCO3?
The answer to the conversion is that 35.0 grams of hydrochloride (HCL) equals 0.76 moles. The conversion rate is 35.0 grams divided by 46 gram per mole. A mole is the molecular weight of a substance.
What is the molarity of a solution prepared by dissolving 1.56 grams of gaseous HCl in enough water to make 26.8 mL of solution?
Find moles of HCl first. 1.56 grams HCl (1mole HCl/36.458 grams) = 0.0428 moles HCl Molarity = moles of solute/volume of solution Molarity = 0.0428 moles/26.8 ml = 0.00160 milli-Molarity, or more to the point; = 1.60 X 10^-6 Molarity of HCl
