Answer» Molar mass of H2SO4 = 98g/mol = MmD =density = 1.84g/ccW/w = 98%V = 1dm3 = 1L = 1000ml = 1000ccMass of solution = V x DM = 1000 x 1.84 = 1840g per 1000ccUsing w/w, 98% of 1840g = H2SO4= (98/100) x 1840 = 1803.2g = mNos of moles = m/Mm = 1803.2/98 = 18.4moles per 1000ccThus, molarity = 18.4M (18.4mol/dm3 |
