Apr 28, 2020 · mg(oh)2 + 2hno3 ==> mg(no3)2 + 2h2o From the equation it takes 1/2 mol Mg(OH)2 to neutralize 1 mol HNO3 so it will take 1/2 x 4.42 = …
Jun 27, 2017 · This means that a complete neutralization will require. 0.0025moles HCl ⋅ 1 mole Mg(OH)2 2moles HCl = 0.00125 moles Mg(OH)2. Finally, to convert this to grams, use the molar mass of the compound. 0.00125moles Mg(OH)2 ⋅ 58.32 g moles Mg(OH)2 = 0.073 g −−−−−−. The answer is rounded to two sig figs. Answer link.

According to the reaction 2Al+3H2SO4→3H2+Al2 (SO4)3, the total number of moles of H2SO4 needed to react completely with 5.0 mol of AL is 1. 2.5 mol 2. 5.0 mol 3. 7.5 mol 4. 9.0 mol
Nitric acid, HNO3, was first prepared 1200 years ago by heating naturally occurring sodium nitrate (called saltpeter) with sulfuric acid to produce sodium bisulfate and collecting the vapors of HNO3 produced. Calculate ΔH°rxn
How many milliliters of 0.100 M HNO3 are needed to neutralize the following solutions? A. 45.0 mL of 0.667 M KOH B. 58.5 mL of 0.0100 M Al (OH)3
Calculate the volume of 0.300M HNO3 needed to complete neutralize 25.0ml of 0.250M Sr (OH)2
The number of moles of acid that can be neutralized by a single tablet of a commercial antacid will be determined by back titration. To do the experiment, an antacid tablet will be dissolved in a known excess amount of acid. The resulting solution will be acidic because the tablet did not provide enough moles of base to completely neutralize ...
The indicator is usually an organic dye that behaves as a weak acid or a weak base.
An acid is a source of aqueous H+ (aq). For example, HCl (aq) is the acid in your stomach: HCl (aq) → H+ (aq) + Cl– (aq). In a healthy stomach, pH is regulated naturally and digestion functions properly when the pH is around 3 (recall neutral is pH = 7). Excess stomach acid can be combated with bases, or "antacids".
Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight ...
