Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. (The molar mass of AgBr is 188 g mol 1 One point is earned for the calculation 71 4 1 mol AgBr 5.0 g AgBr 0.0266 mol AgBr 188 g AgBr 0.0266 mol of moles of dissolved AgBr. CLICK HERE, International Order of the Rainbow for Girls. You can see that in AgBr, there is 1 Silver atom and 1 Bromine atom. Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. common chemical compounds. a. We will calculate hydroxyl ion concentration from the buffer, A: Equilibrium constant (Keq) is the ratio of the concentration of products to the concentration of, A: dear student,since you have asked multiple questions but according to guidelines we will solve 1st, A: Solubility product (Ksp):- answered 11/10/17, Ph.D. University Professor with 10+ years Tutoring Experience. Step One: Write balanced equation The reaction above is not balanced. Convert between AgBr (ag) weight and moles. Bronsted Lowry Base In Inorganic Chemistry. Provide your answer below: Problem 1RQ: Define and explain the differences between the following terms. Clergy & Staff Contacts. C) Rusting of iron D) Neutralization of HCl by NaOH Mole of AgNO3 in 3.84 g = (3.84 g/169.91 g/mol) = 0.0226 mol. By using this website, you signify your acceptance of Terms and Conditions and Privacy Policy. For this reaction, equilibrium constant is Keq, A: The equilibrium between the soluble ions and insoluble salt can be described by the solubility, A: To calculate maximum dissolved [Mg2+] , You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
