After dilution with water to 5.20-molar, the solution has a density of 1.38 grams per milliliter and can be used a san electrolyte in lead storage batteries for automobiles.a) Calculate the volume of concentrated acid required to paper 1.00 liter of 5.20-molar H2SO4 b) Determine the mass percent of H2SO4 in the original concentrated solutionc) Calculate the volume of 5.20-molar H2SO4 that can be completely neutralized with 10.5 grams of sodium bicarbonate, NAHCO3d) What is the molality of the 5.2-molar H2SO4 ?*molarity = mole of soulate / solution( L ) *molality = mole of soulate / solvent (kg) *GFM of H2SO4 = 98 鏈接文章 分享到其他網站
