It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is an inorganic compound with the formula Ag 2S. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Want to see the step-by-step answer? Convert grams Silver Sulfide to moles  or  moles Silver Sulfide to grams, Molecular weight calculation: Write the compound name for the following formulas and determine the molar mass: A. Ag2S. Question. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Calculate Ksp for Ag2S. To find more Silver sulfide information like chemical properties, structure, melting point, boiling point, density, molecular formula, molecular weight, physical properties and toxicity information. These relative weights computed from the chemical equation are sometimes called equation weights. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. 2Ag + +S(2-) = AgS 2AgNO3 + Na2S = AgS + 2NaNO3. Image Transcriptionclose. 0.747 g to 3 S.F. This video contains plent The solubility of Ag2S is measured and found to be 7. molar mass and molecular weight. We use the most common isotopes. These relative weights computed from the chemical equation are sometimes called equation weights. 357.49 g/mol. E. N2S4. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Solubility in water, . Browse the list of This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. D. Fe3(PO4)2. Categories: Inorganic salt. Calculate the molecular weight Formula: Ag2S. SOT-23. Actually a limiting reactant question. The solubility table below gives the maximum mass of solute in grams that can be dissolved in 100 mL of water at 25°C. so there is a slight difference. 107.8682*2 + 32.065. Molar mass of Ag2S is 247.8014 g/mol Compound name is silver sulfide Convert between Ag2S weight and moles 0 0. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). molar mass and molecular weight. 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. Ag2S is a black crystal at room temperature, density 7.23 g/cm 3 , melting point 825 C. It is insoluble in water, but soluble in strong acids, including nitric acid. Solution for The molar solubility of Ag2S is 1. 2Ag + +S(2-) = AgS 2AgNO3 + Na2S = AgS + 2NaNO3. So, the number of mol {eq}(N) {/eq} of {eq}Ag_2S {/eq} present in 125 g of mass {eq}(M) {/eq} is calculated as shown below: This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. A common request on this site is to convert grams to moles. A common request on this site is to convert grams to moles. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. Molecular weight calculation: 107.8682*2 + 32.065 ›› Percent composition by element 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. Calculate Ksp for Ag2S fullscreen. We use the most common isotopes. Definitions of molecular mass, molecular weight, molar mass and molar weight. The reason is that the molar mass of the substance affects the conversion. 10 years ago. See Answer. Convert grams Silver Sulfide to moles or moles Silver Sulfide to grams. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Check out a sample Q&A here. This site explains how to find molar mass.
