Molecular weight is often used interchangeably with molecular mass in chemistry, although technically there is a difference between the two. Molecular mass is a measure of mass and molecular weight is a measure of force acting on the molecular mass. A more correct term for both molecular weight and molecular mass, as they are used in chemistry .

Sep 02, 2009· So the rule is to divide the molecular weight of an acid by the number of replaceable H atoms; divide the molecular weight of a base by the number of OH groups; and divide the molecular weight of a salt by the number of H's or OH's that reacted to form it. The equivalent weight of HCl is 36.5/1 = 36.5. The equivalent weight of H2SO4 is 98/2 = 49.

CaCl 2 additive is effective at temperatures between 40° and 120°F (4° and 49°C) in concentrations of 2% to 4% by weight of cement (bwoc), or equivalent liquid concentrations of 40 gal/100 sk (2%).

Sep 08, 2006· I'm doing an Equivalent Weight and Normality experiment and I got very confused on the discussion questions.[ the unknown is titrated with the KMnO4] 1) In this experiment MnO4- is reduced to Mn2+ by the unknown. What is the equivalent weight of MnO4- for . …

How many grams of CaCl2 (molar mass = 111.0 g/mol) are needed to prepare 3.03 L of 0.500 M CaCl2 solution? a. 180 g b. 168 g c. 193 g d. 291 g e. 218 g

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

Jul 06, 2013· Equivalent weight = Molecular weight ÷ Total positive charge. Number of moles = mass ÷ molecular weight. Number of equivalents = mass ÷ equivalent weight. Example: For CaCl2, the total positive charge is +2. For CaCl2, the molecular weight is 111.1 grams. Equivalent weight = 111.1 ÷ 2 = 55.55 grams.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.

If you are dealing with other units, say pounds, as a unit of weight, 'then 1 kg corresponds to 2.21 lb at sea level in the sense that the weight of 1 kg is 2.21 lb at sea level. Similarly 1 lb corresponds to 453.6 g and 1 oz to 28.35 g' (Beiser, A. Physics, 5th ed, Addison Wesley, 1992)

Calcium Carbonate (CaCO 3) Equivalent. An expression of the concentration of specified constituents in water in terms of their equivalent value to calcium carbonate. For example, the hardness in water that is caused by calcium, magnesium, and other ions is usually described as calcium carbonate equivalent.

Molarity. In chemistry, molar concentration, or molarity, is defined as moles of solute per total liters of solution. This is an important distinction; the volume in the definition of molarity refers to the volume of the solution, and not the volume of the solvent.The reason for this is because one liter of solution usually contains either slightly more or slightly less than 1 liter of solvent .

Equilibrium constant of a reaction is related to the temperature of the system. By Van't Hoff equation the change is in equilibrium is associated to the change in standard enthalpy.

As the energy released from the hydration energy is sufficient to compensate for the energy required to break down the ionic lattice of CaCl2,CaCl2 dissolves in water. The excess energy not used to break down the lattice is released as heat (exoth.

Apr 30, 2018· For NaCl, the valence is 1 because only one hydrogen atom could bond with NaCl. For H2SO4, or sulfuric acid, the valence is 2 because two hydrogen atoms bond with sulfate, or SO4. Divide the molecular weight by the valence to calculate the equivalent weight. The equivalent weight of NaCl is 58.443/1 or 58.443.

Sep 05, 2016· The weight in grams of one equivalent of a substance. Equivalence point. The point in a titration where the number of equivalents of titrant is the same as the number of equivalents of analyte.

Video transcript. That seems like a very simple answer. Well you say, OK, well, one equivalent would then be one mole of potassium. Or you could even rephrase it. You could say, well, in one mole of potassium-- and this is how people usually use the phrase. They say, well, 1 mole of potassium equals 1 equivalent.

A metric ton is a unit of weight and liter is a unit of volume. Equally, the cup is a unit of volume and the gram a unit of weight. To complete a calculation such as this, you therefore have to factor in the density of the substance that you are trying to convert and include that in the formula calculation.

equivalent is ½ of one mole, since each mole of CaCO3 neutralizes two moles of H And again, the equivalent weight is ½ the molecular weight. Put another way, K (which is an expression of the number of equivalents supplied per

Mg2+ valence is +2, so equivalent weight is 24/2 = 12 Na2CO3 valence is +2, so equivalent weight is 106/ 2 = 53 Equivalent weight does not have signs so if you find the valence of any sign, use the numerical value and molecular weight, divide the molecular weight with the numerical value of …
