You are given the three white powders calcium carbonate, lead carbonate and zinc carbonate. Find the total percentage of Magnesium in magnesium nitrate crystals, Mg(NO3)2. asked Feb 28, 2019 in Chemistry by Anjal (76.7k points) mole concept; stoichiometry; icse; class-10; 0 votes. Magnesium dinitrate reacts with alkali metal hydroxide to produce the following: Mg(NO 3) 2 + 2 NaOH → Mg(OH) 2 + 2 NaNO 3. Write the simplest ionic equation, including state symbols, for any reaction that Join now. ... Identify the white precipitate and calculate the percentage, by mass, of magnesium ... added separately to aqueous magnesium sulfate and to aqueous magnesium nitrate. This means that in every sample of this substance there is the same number of Oxygen and Magnesium atoms.. From the periodic table we see that the atomic masses are 24.3 (Mg) and 16.0 (O).
