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