The gram-equivalent weight of the OH -ion is 16.000 + 1.008 = 17.008 g and of the Ca ++ ion is … Acceleration (a) of an object measures the object's change in velocity (v) per unit of time (t): a = v / t. st/mm³ to long tn/US tbsp conversion table, st/mm³ to long tn/US tbsp unit converter or convert between all units of density measurement. This compound is also known as Borax. 5H 2 O, 25% Cu). Borax can also be used as the cleansing … To get it's equivalent weight as an acid you have to divide by the number of replaceable H atoms, in this case, 3 . Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, … The name “borax” is derived from the word “borak,” which means white in Persian. For comparison's sake, the LD 50 of salt is reported to be 3.75 g/kg in rats according to the Merck Index. Lower dose for low to normal weight - 100 ml (= 1/8 teaspoon of borax powder); drink spaced out during the day. 1 mole is equal to 1 moles Borax, or 381.37214 grams. Complex ion. Equivalent weight. The equivalent weight of boric acid is 20,61 g. Boric acid is indeed used for ant control, but boric acid is a lot more famous for it's use in roach control. The SI base unit for amount of substance is the mole. Enter volume, select a unit of volume, and specify a material or substance to search for. Therefore, the FAS equivalent weight is equal to its molecular weight. 5 years ago. The molecular weight of the ferrous ammonium sulfate is. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. The reported acute oral LD 50 for boric acid in mice is 3450 mg/kg. = 0.4421 mg/m3(or 1 mg/m3= 2.262 ppm.). The ion is [B 4 O 5 (OH) 4] 2− and the remaining eight water molecules are associated with the two sodium ions. Further details about wire preparation as well as the borax bath may be referred to in “Borax in Wire Drawing” published by Borax Consolidated Limited, 1973. Acid. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Syn. Copper. 0 0. Calculate volume of a hollow cylinder and its surface area. Eequivalent weight Calculations. with a single dose of borax or boric acid (50% wfv in 0.5% aqueous methyl cellulose or distilled water suspension). We supply 30% of the world’s need for refined borates from our world-class mine … This site explains how to find molar mass. Another way of looking at it is that the 8.5g represents 0.05 equivalents (0.1Eq/L x0.5L). 9. The molecular weight of the tetraborate is 201.22 and that of its decahydrate is 381.37. = Molecular weight/n-factor. It usually exist in the form of white powder or colorless crystal. COMPONENT: SODIUM TETRABORATE DECAHYDRATE (BORAX) CAS# 1303-96-4 10 mg/m3 OSHA TWA 5 mg/m3 ACGIH TWA Carcinogen status of component: Not listed as a carcinogen by NTP, IARC, or OSHA. of a chemical compound, More information on Molar mass of Na2B4O7.10H2O = 381.37214 g/mol, Convert grams borax to moles  or  moles borax to grams, Molecular weight calculation: Finding molar mass starts with units of grams per mole (g/mol). 22.98977*2 + 10.811*4 + 15.9994*7 + 10*(1.00794*2 + 15.9994). density of borax is equal to 1 730 kg/m³.In Imperial or US customary measurement system, the density is equal to 108 pound … Sometimes, however, the amount of boron used in toxicity testing can be … Many people seek out borax substitutes after learning a bit more about this unusual substance. Calculate how much of this gravel is required to attain a specific depth in a cylindrical,  quarter cylindrical  or in a rectangular shaped aquarium or pond  [ weight to volume | volume to weight | price ], Cesium [Cs] weighs 1 930 kg/m³ (120.48596 lb/ft³)  [ weight to volume | volume to weight | price | mole to volume and weight | mass and molar concentration | density ], Volume to weight,  weight to volume and cost conversions for Refrigerant R-22, liquid (R22) with temperature in the range of -51.12°C (-60.016°F) to 71.12°C (160.016°F), The pound per cubic inch density measurement unit is used to measure volume in cubic inches in order to estimate weight or mass in pounds. Theoretical Equivalent weight of ammonium hydroxide (NH 4 OH) = 35.00 g/equivalent of OH-Reasoning: 35.00g/mol of NH 4 OH * (1 mole NH 4 OH / 1 equivalent of OH-) = 35.00 g/equivalent of OH- In borax, two boron atoms are in triangular geometry and two boron atoms are in tetrahedral geometry. The equivalent weight of boric acid is 20,61 g. Boric acid is indeed used for ant control, but boric acid is a lot more famous for it's use in roach control.
