1. what is the volume of 2.00M solution of sulfuric acid required to react with 250g of carbonate of magnesium according to the following reaction?

MgCO3 + H2SO4 -> MgSO4 + CO2 + H2O

Answer 1

solution I Given Mg (O3 + H₂ 50 MgSO4 + CO₂ + H₂O = 2:00 moles concentration of H2SO4 = 2.00M Mass of mgco z = 250 g Molar Mass of Mg 10 3 = 84.3 g/mol - Neembere of moles of Mg 103 = mass of 199103 molar mass of 1903 = 250g - 84.3 g/mol = 2.97 mal since by stoichiometry I mole of MgCO3 needs 1 mole of H2SO4 = 2.97 males of Mg 20 3 requiries = 2.97 moles of 1 H₂SO4 concentration of H2SO4 = number of moles of H₂SDA volume of solution volume of solution of H₂SO4 = 2.97 moles of 12804 2.80 moles / =111485 h
