How do you calculate 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.
What is caco3 equivalent weight?
= 1 × 40 +1 × 12 + 3 × 16. = 40 + 12 + 48. = 100. The molecular weight of the calcium carbonate is 100. ∴ The equivalent weight of the calcium carbonate is = 100/2 = 50.
What is meant by equivalent weight?
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 the equivalent weight of k2 cr2 o7?
49g/eq
Hence, the equivalent weight of ${K_2}C{r_2}{O_7}$ in acidic medium will be 49g/eq.
How do you calculate molar equivalent weight?
Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.
Is equivalent weight and gram equivalent same?
In chemistry, 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.

What is the equivalent weight of nahco3?
The equivalent weight of Sodium Bicarbonate ( ) is 84 gm/mol.
What is the unit of equivalent weight?
grams
The unit of equivalent weight is the atomic mass unit; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent. Hydrogen has atomic weight 1.008 (rounded to three decimal places) and always assumes valence 1 in compounds, so its equivalent weight is 1.008.
What is the equivalent weight of feso4?
So, the molecular weight of ferrous sulphate is 151.8. -Equivalent weight of ferrous sulphate = molecular weight of ferrous sulphate/ involved electron. So, equivalent weight of ferrous sulphate which is present as reductant is 151.8 which is equal to the molecular weight of ferrous sulphate.
