Magnesium Hydroxide is a solution of magnesium hydroxide with antacid and laxative properties. Milk of magnesium exerts its antacid activity in low doses such that all hydroxide ions that enter the stomach are used to neutralize stomach acid. Calculate the formula weight (in amu) and molar mass (in g/mol) for magnesium hydroxide, Mg(OH)2. 0 0. Woman arrested after driving car into Calif. protest. Answer Save. Relevance. Molar mass of barium hydroxide, Ba(OH)2 = 171.3Amount of barium hydroxide = mass of sample / molar mass = 317.0/171.3 = 1.85mol Molar Mass Of Magnesium from gas … The molar mass of a substance, also often called molecular mass or molecular weight (although the definitions are not strictly identical, but it is only sensitive in very defined areas), is the weight of a defined amount of molecules of the substance (a mole) and is expressed in g/mol. I hope this helps! Source(s): My paper & pencil. 8 Answers. Note that rounding errors may occur, so always check the results. Mg = 24.31. Lv 4. were purified before use. Mg: 1 x 24.31 g = 24.31 g. O: 2 x 16.00 g = 32.00 g. H: 2 x 1.01 g = 2.02 g ===== Mg(OH)2 = 58.33 g. Recall that percent, in general, is given by (part/whole) x 100. Consider the mass of Mg(OH)2. Erika. Ammonium persulfate (APS, from Junsei Chem. The SI base unit for amount of substance is the mole. Structure, properties, spectra, suppliers and links for: Magnesium hydroxide, 1309-42-8, 1317-43-7, 1909-42-8, Magnesia, [Milk of]. %O = (32.00 g/58.33 g) x 100 = 54.86. IIwintermuteII. O = 2(16.00) H = 2(1.01) Formula Weight = 24.31 + 2(16.00) + 2(1.01) = 58.32 amu. 1 mole is equal to 1 moles Magnesium Hydroxide, or 58.31968 grams. Use this page to learn how to convert between moles Magnesium Hydroxide and gram. First person to put the correct answer with explanation of work gets a best answer! 1 decade ago. molecular weight of Magnesium Hydroxide or grams The molecular formula for Magnesium Hydroxide is Mg(OH)2. Favourite answer. In this case, that is ((mass of oxygen)/(mass of magnesium hydroxide)) x 100. Magnesium hydroxide (provided from Skynics), with average particle size of 50 nm, was dried at 110°C under vacuum for 24 h prior to use. Lv 4. Molar Mass is the … Nike 'just getting started' after wowing investors 3-(Trimethoxysilyl) propyl methacrylate (γ-MPS, from Sigma-Aldrich) and methyl methacrylate (MMA, from Junsei Chem.)
