How do you find the equivalent mass of h2so4?

20
Equivalent weights may be calculated frommolarmasses if the chemistry of the substance is wellknown:sulfuric acid has a molar mass of 98.078(5)gmol−1, and supplies two molesofhydrogen ions per mole of sulfuric acid, soitsequivalent weight is 98.078(5)gmol−1/2eqmol−1 = 49.039(3)geq−1.


Accordingly, what is the formula of equivalent mass?

It is easy to find the equivalent mass forthesecompounds: divide the molar mass of the compound bythevalence of the element differing from oxygen by the number ofitsatoms. Let's look at the equivalent mass for gold oxidewiththe formula Au2O3. With simple calculations we get:1972+163divided by 3*2= 73.7 g/mol.

Furthermore, what is equivalent mass of HCl? Examples. 1) The gram-equivalent weight of HClisone mole of HCl (1.008 + 35.453 = 36.461 g). 2)Thegram-equivalent weight of H2SO4isusually ½ mole since both hydrogens are replaceable inmostreactions of sulfuric acid.

Keeping this in consideration, how do you find the molecular weight of h2so4?

This chemical is used as achemicalintermediate to manufacture other chemicals andcleaning metalsurfaces. The formula for sulfuric acidisH2SO4. The molar mass of sulfuric acid is 98.07848gmol.

How do you find the equivalent mass of NaOH?

The equivalent mass of NaOH is 40 grams. Itisaccording to the formula , Gram molecularweightdivided by the 'n' factor. 'n' factor will be 1because in case ofionic compounds we need to take the total chargepresent on onetype of i.e. either that of the cation or that oftheanion.

What is normality formula?

It is defined as the gram equivalent weight per literofsolution. Here, a more favorable calculationfornormality is considered, where the normality ofasolution is equal to the molarity multiplied by the numberofequivalents. Normality(N) = Molarity(M) x numberofequivalents. Normality Formula Questions: 1.

What is meant by normality?

Normality is a measure of concentration equaltothe gram equivalent weight per liter of solution. Gramequivalentweight is the measure of the reactive capacity of amolecule. Thesolute's role in the reaction determines thesolution'snormality. Normality is also known as theequivalentconcentration of a solution.
