Can equivalent weight be more than molecular weight?
STATEMENT – 1 : Equivalent weight of a substance can never be greater than its molecular weight.
What is the relationship between the equivalent weight and molecular weight?
Equivalent Weight. The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). In this example, the magnitude of the equivalent weight of sulfuric acid is HALF of that of the molecular weight.
What is the difference between equivalent weight and weight?
Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. Equivalent weight has the dimensions and units of mass, unlike atomic weight, which is dimensionless.
Can a substance have both a formula weight and a molecular weight?
The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. The molecular mass (molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.
Which compound has same equivalent weight and molecular weight?
NaCl has the same equivalent weight and molecular weight.
Which of the following compound has the same molecular weight and equivalent weight?
H3PO4 basicity is 1. Therefore its molecular weight and equivalent weight are same.
What is difference between weight and molecular weight?
Moreover, the main difference between both is that molar mass gives the mass of a mole of a particular substance. Whereas molecular weight is the mass of a molecule of a particular substance….Difference Between Molar Mass and Molecular Weight.
Basis | Molar Mass | Molecular Weight |
---|---|---|
Unit | Kgmol-1 | Atomic mass units |
What is difference between molecular formula and molecular weight?
Formula weight is the sum of weights of all the atoms in an empirical formula of a molecule. Molecular weight is the collection of weights of all the atoms in a molecular formula.
What is equivalent weight of a compound?
equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction.
What is molecular equivalent?
Mole concept is based on molecular weight. An equivalent concept is “gram equivalent weight” or “gram equivalent” concept. It is based on equivalent weight. Equivalent weight is measure of mass proportion of an element, compound or ion in which it combines with the mass of other chemical entities.
What is the molecular weight of a compound?
The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). Examples: (1) H 2SO 4 + 2OH -= 2H 2O + SO 4 2-. Molecular weight of sulfuric acid (H 2SO 4) = 98.07 g/mol.
What does equivalent weight mean in chemistry?
Definitions of Equivalent Weight ( Acid-Base Context ) The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). Examples: (1) H 2SO 4 + 2OH -= 2H 2O + SO 4 2-. Molecular weight of sulfuric acid (H 2SO 4) = 98.07 g/mol.
Can the equivalent molecular weight be greater than the molar mass?
Molecular mass/weight is always in the numerator, “n” in the dominator. n has to be 1 or a greater whole number. So equivalent weight must equal molecular weight or some simple fraction (<1) of it. Yes. It can be greater than molar mass if Nfactor is in range (0,1).
How do you calculate the number of equivalents of a compound?
The general number of equivalents formula is E = MW/charge number Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound contains.
