For example, Equivalent weight of acid = molecular weight of acid/basicity of acid The acid H2SO4 can donate 2 hydrogens. 1 + Wt. It is essential to determine the Epoxy Equivalent Weight (E.E.W.) of the mixture to determine proper stoichiometric ratios with the curing agent. Thanks. Fluorine is the ion (F-1) and its molar mass is 19 g. • When calculating Pressure Reduction Schedule, ROUND DOWN to a whole number (for example: round down 21.6 psi/100 stks to 21 psi/100 stks). Share Tweet Send [Deposit Photos] The equiv­a­lent of a sub­stance, also known as the equiv­a­lent quan­ti­ty of a sub­stance, refers to the quan­ti­ty of a sub­stance that in­ter­acts with one mole … Calculating equivalent mass Defining the equivalent of a substance. For example, consider the reaction, H 3 PO 4 → HPO 4 2-+ 2H + The molecular weight of a chemical reaction is 98, and the valency is 2, then the equivalent weight of H 3 PO 4 is. equivalent weight: The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. • When calculating Leak Off Test Equivalent Mud Weight, ROUND DOWN to one decimal place (for example: round down 11.76 ppg to 11.7 ppg; round down 13.89 ppg to 13.8 ppg). Print Equivalent Weight: Definition & Formula Worksheet 1. This is accomplished with the following equation: Equation 1: E.E.W. of Mixture = Total Weight of Mixture Wt. Equivalent weight of Oxidising and Reducing Agents. A metal oxide contains $60$% metal.The equivalent weight of metal is (1) $12$ (2) $60$ (3) $40$ (4) $24$ I know that the equivalent weight of metal oxide = equivalent weight of metal + 8.But how can i arrive at the answer with this. 2 E.E.W. What is the correct setup to determine the equivalent weight (EW) of fluorine? Name Formula Molecular Weight Equivalent Weight Aluminum Sulfate Al 2(SO 4) 3 18H 2O 666. Examples: (1) H 2 SO 4 + 2OH-= 2H 2 O + SO 4 2-Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol . The equivalent weight of an element or radical is equal to the ratio of it's atomic weight or formula weight devided by it's valency. Theoretical Equivalent weight of sulfuric acid (H 2 SO 4) = 49.03 g/equivalent of H + Reasoning: Equivalent weight of a substance (oxidant or reductant) is equal to molecular weight divided by number of electrons lost or gained by one molecule of the substance in a redox reaction. The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). 1 E.E.W. Learn more about Appendix 2: Molecular and Equivalent Weights on GlobalSpec. Equivalent weight depends on type of the substance. The formula to calculate the equivalent weight is given as: Equivalent Weight = Molecular weight/ Valency. g eq−1kg eq−1. 2 Example 1: A mixture of 80% Liquid Epoxy Resin (E.E.W.
