What is the difference between gram equivalent and equivalent mass?
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.
What do you mean by gram equivalent?
Definition of gram equivalent : the quantity of an element, group, or compound that has a mass in grams equal to the equivalent weight.
What is its equivalent mass in grams?
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.
How is equivalent mass calculated?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.
How do you find the gram equivalent?
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.
What is gram equivalent mass Class 11?
Gram equivalent mass is a quantity that is numerically equal to the equivalent weight. Explanation. Gram equivalent is defined as the amount of substance that is numerically equal to its equivalent weight expressed in grams.
How do you calculate gram equivalent mass of HCl?
Now equivalent mass is given as the molecular weight divided by the n-factor. Therefore, the equivalent mass of HCl is 85.1g.
What is the equivalent mass of Ca Oh 2?
The equivalent weight of calcium hydroxide is 1/2 he mass of a mol of calcium hydroxide. 1 mol Ca(OH)2 = 74 grams Ca(OH)2 ; 1 equivalent Ca(OH)2 = 37 grams Ca(OH)2……
What is the equivalent mass of NaOH?
40 g/mol
The equivalent weight of sodium hydroxide NaOH is 40 g/mol.
How do you calculate gram equivalent?
What is the difference between gram equivalent and 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. The below infographic summarizes the difference between gram equivalent and equivalent weight.
What does equivalent mass mean in chemistry?
The quantity of an element, group, or compound that has a mass in grams equal to the equivalent weight. Equivalent mass: The mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen : the atomic or molecular weight divided by the valence.
What is the equivalent weight of a substance?
Equivalent weight (also known as gram equivalent) is a term which has been used in several contexts in chemistry. In its most general usage, it is the mass of one equivalent, that is the mass of a given substance which will
What is the mass of an element in grams?
For an element, it is the weight (in grams) that combines with or replaces 1.00797g of hydrogen or 7.9997g of oxygen. Or, it is the weight of an element which is liberated during electrolysis. Dwayne is in hot water for his latest comments.
