• 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). of Mixture = Total Weight of Mixture Wt. Name Formula Molecular Weight Equivalent Weight Aluminum Sulfate Al 2(SO 4) 3 18H 2O 666. Equivalent weight depends on type of the substance. 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. It is essential to determine the Epoxy Equivalent Weight (E.E.W.) Thanks. 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. 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. 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. This is accomplished with the following equation: Equation 1: E.E.W. Any help appreciated. Fluorine is the ion (F-1) and its molar mass is 19 g. Learn more about Appendix 2: Molecular and Equivalent Weights on GlobalSpec. of the mixture to determine proper stoichiometric ratios with the curing agent. Theoretical Equivalent weight of sulfuric acid (H 2 SO 4) = 49.03 g/equivalent of H + Reasoning: The formula to calculate the equivalent weight is given as: Equivalent Weight = Molecular weight/ Valency. 2 E.E.W. 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 … 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 2 SO 4 + 2OH-= 2H 2 O + SO 4 2-Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol . g eq−1kg eq−1. Calculating equivalent mass Defining the equivalent of a substance. Equivalent weight of Oxidising and Reducing Agents. 1 E.E.W. 1 + Wt. Print Equivalent Weight: Definition & Formula Worksheet 1. For example, Equivalent weight of acid = molecular weight of acid/basicity of acid The acid H2SO4 can donate 2 hydrogens. • 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). What is the correct setup to determine the equivalent weight (EW) of fluorine? 2 Example 1: A mixture of 80% Liquid Epoxy Resin (E.E.W.
