Magnesium Hydroxide is a solution of magnesium hydroxide with antacid and laxative properties. The SI base unit for amount of substance is the mole. 8 Answers. were purified before use. Consider the mass of Mg(OH)2. Favourite answer. 1 mole is equal to 1 moles Magnesium Hydroxide, or 58.31968 grams. 3-(Trimethoxysilyl) propyl methacrylate (γ-MPS, from Sigma-Aldrich) and methyl methacrylate (MMA, from Junsei Chem.) Mg = 24.31. Use this page to learn how to convert between moles Magnesium Hydroxide and gram. 0 0. In this case, that is ((mass of oxygen)/(mass of magnesium hydroxide)) x 100. Erika. 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. %O = (32.00 g/58.33 g) x 100 = 54.86. IIwintermuteII. Woman arrested after driving car into Calif. protest. 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. Note that rounding errors may occur, so always check the results. Answer Save. Nike 'just getting started' after wowing investors Lv 4. Structure, properties, spectra, suppliers and links for: Magnesium hydroxide, 1309-42-8, 1317-43-7, 1909-42-8, Magnesia, [Milk of]. O = 2(16.00) H = 2(1.01) Formula Weight = 24.31 + 2(16.00) + 2(1.01) = 58.32 amu. Ammonium persulfate (APS, from Junsei Chem. I hope this helps! 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 … Relevance. Molar Mass is the … Calculate the formula weight (in amu) and molar mass (in g/mol) for magnesium hydroxide, Mg(OH)2. 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. molecular weight of Magnesium Hydroxide or grams The molecular formula for Magnesium Hydroxide is Mg(OH)2. 1 decade ago. Lv 4. First person to put the correct answer with explanation of work gets a best answer! Source(s): My paper & pencil. 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.
