The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Favorite Answer. Chemical formulas are case-sensitive. using a ratio of % 's. calculate the mass of silver chloride required to plate 155 mg of pure silver. Counting the number of atoms of each element in the compound. silver chloride, often used in silver plating, contains 75.27% Ag by mass.? When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Molar mass of silver is 107.86820 ± 0.00020 g/mol Compound name is silver Convert between Ag weight and moles To convert this mass to moles, use the molar mass of silver chloride. Silver chloride is prepared when sodium chloride is added to silver nitrate solution a white precipitate of silver chloride occurs. Example Reactions: • AgNO3 + KCl = AgCl↓+ KNO3. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Silver chloride in the test tube quickly turns purplish, especially in a sunny laboratory because the silver chloride is split up into silver and chlorine. Silver chloride, often used in silver plating, contains 75.27% Ag. Bromide Iodide. Textbook solution for Living By Chemistry: First Edition Textbook 1st Edition Angelica Stacy Chapter U4.26 Problem 6E. mol −1: Related compounds Other anions. Calculate the mass of silver chloride required to plate 165 mg of pure silver? Silver chloride undergo decomposition reaction in the presence of sunlight to form silver and chlorine. • AgNO3 + NH4Cl = AgCl↓+ NH4NO3. AgCl → Ag + Cl. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. A chloride ion is much larger than a chlorine atom, 167 and 99 pm, respectively. Convert grams Silver Chloride to moles or moles Silver Chloride to grams, Molecular weight calculation: Formula: AgCl. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. This site explains how to find molar mass. Relevance. Molar Mass: 143.3212. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. of a chemical compound, More information on Molar mass of AgCl = 143.3212 g/mol. Calculate the molecular weight Answer Save. Calculate the mass of silver chloride required to plate 165 mg of pure silver? To complete this calculation, you have to know what substance you are trying to convert. Convert grams Silver Chloride to moles or moles Silver Chloride to grams. amount of AgCl is 4.8/0.7527, or 6.377 grams. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). The ion is colorless and diamagnetic. 107.8682+35.453. molar mass and molecular weight. In aqueous solution, it is highly soluble in most cases; however, for some chloride salts, such as silver chloride, lead (II) chloride, and mercury(I) chloride, they are slightly soluble in water. Steve O. Lv 7. Molecular weight calculation: 107.8682 + 35.453 ›› Percent composition by element If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Molar mass of AgCl, Silver Chloride is 143.3212 g/mol. A common request on this site is to convert grams to moles. ›› Silver Chloride molecular weight. or . 0.165 g Ag @ (100 % AgCl) / (75.27% Ag) = 0.219 g of AgCl would be required .
