How do you calculate equivalents in chemistry?
To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.
What is the formula of equivalent?
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
What is the formula to calculate equivalent weight?
Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.
What are equivalents in chemistry?
An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction.
How do you calculate the number of gram equivalents?
Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n. Here we will learn how to calculate the Equivalent Weight Formula of a compound.
How do you calculate electron equivalents?
1 electron equivalent (eeq) of some electron donor (e.d.) = amount of the substance which releases 1 mol e– during a specified oxidation reaction. in which 1 eeq Fe = 1/3 mol Fe.
What is the equivalent of caco3?
The equivalent weight of calcium carbonate (CaCO3) is 50.045, as calculated above.
How do you calculate mEq L?
The equation to get mEq is therefore [(30 mg)(2)]/(58.44 mg/mmol) = 1.027 mEq. Since there are 400 mL = 0.4 L, the concentration in mEq/L is therefore 1.027/0.4 = 2.567 mEq/L.
How do you find the number of gram equivalents?
What is an equivalent in organic chemistry?
Illustrated Glossary of Organic Chemistry – One equivalent. One equivalent: In reaction stoichiometry, the amount of one substance that reacts with one mole of another substance.
What is the equivalent weight of NaCl?
The equivalent weight of NaCl is 58.5/1 or 58.5.
How do you calculate equivalent energy?
The E = mc2 equation represents the idea that energy and mass are correlated, that any object with mass corresponds to an equivalent amount of energy. This equation is Einstein’s special theory of relativity in mathematical terms. The E = mc2 calculator can solve for E or m.
What is the equivalent weight of mgso4?
The molecular weight of magnesium sulphate is 120.366 g/mol.
What is the equivalent weight of h2so4?
Sulphuric acid contains two replaceable hydrogen. Hence, the equivalent weight of sulphuric acid is 49u.
How do you calculate mEq to ML?
Cross Multiply: 40 mEq * Xml = 10 mEq * 200 ml. Now calculate the drip rate for the infusion….Medication Calculation.
| 1 kilogram (kg) | 2.2 pounds (lb) |
|---|---|
| 1 gram (g or gm) | 1000 mg (milligrams) |
| 1 milligram (mg) | 1000 micrograms (mcg) |
| 1 gram (gm) | 1 ml (milliliter) |
How do you calculate mEq to mg?
- To convert milligrams to milliequivalents use the formula: mEq = (mg x valence) / atomic or molecular weight.
- One thousand milliequivalents equals one equivalent.
How do you calculate equivalents of normality?
Normality Formula
- Normality = Number of gram equivalents × [volume of solution in litres]-1
- Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
- N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
- N = Molarity × Molar mass × [Equivalent mass]-1
What is the difference between gram equivalent and equivalent?
Summary – Gram Equivalent vs Equivalent Weight The key difference between gram equivalent and equivalent weight is that gram equivalent describes that the mass of one equivalent is given in the unit of gram whereas equivalent weight describes the mass of one equivalent in any unit of measurement.
