You are given the three white powders calcium carbonate, lead carbonate and zinc carbonate. [2] (ii) The mass of 5.6 dm 3 of a certain gas at STP is 12.0 g. Calculate the relative molecular mass of the gas. Magnesium oxide has formula MgO (that is, #Mg_1O_1#). Describe the tests you would carry out in solution to identify the metal in each of the above compounds. Magnesium dinitrate reacts with alkali metal hydroxide to produce the following: Mg(NO 3) 2 + 2 NaOH → Mg(OH) 2 + 2 NaNO 3. Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. If the relative molecular mass of ammonium nitrate is 80, calculate the percentage of nitrogen and oxygen in ammonium nitrate. 6H2O Atom percent gives the percentage (contribution) of one atom species in the total number of atomic species present i.e. (Total 7 marks) Q6. Using the same principle, 1 mole of oxygen, nitrogen, and magnesium all have masses equal to their molar mass. asked Feb 28, 2019 in Chemistry by Anjal (76.7k points) mole concept; stoichiometry; ... Find the total percentage of oxygen in magnesium nitrate crystals : Mg(NO3 )2 . (iii) Find the total percentage of oxygen in magnesium nitrate crystals: Mg(NO 3)2.6H 2O. Find the total percentage of oxygen in magnesium nitrate crystals: Mg(NO3)2.6H2O. ,What is the other substance, if any, that remains in the resultant mixture? (H = 1 , N = 14 , O = 16 , Mg = 24) Question 1 [5] (f) You are given the three white powders calcium carbonate, lead carbonate and zinc carbonate. 6H2O.
