Solved Atomic Mass of Magnesium Would a change in - Chegg
WebMar 13, 2024 · Mass magnesium = 2.39 g. Mass magnesium oxide = 3.78 g. So mass oxygen = 1.39 g. Number moles Mg = 2.39/24 = 0.0995. Number moles O = 1.39/16 = 0.0868. Divide by the smallest to give the ratio aproximately 1 Mg : 1 O. This would suggest a formula of MgO, which is the correct formula. How many moles of hydrogen are … WebJul 29, 2024 · For example, the mass of 1 mol of magnesium (atomic mass = 24.305 amu) is 24.305 g. Because the atomic mass of magnesium (24.305 amu) is slightly more than twice that of a carbon-12 atom (12 amu), the mass of 1 mol of magnesium atoms (24.305 g) is slightly more than twice that of 1 mol of carbon-12 (12 g). WebUse this practical to determine the relative atomic mass of magnesium using its reaction with hydrochloric acid. Includes kit list and safety instructions. how do you make a dash before a name
