the molality of 1L solution with x% H2SO4 is 9. The weight of solvent present in the solution is 910g. the value of x is? a. 90 b. 80.3 c. 30.38 d. 46.87 Share with your friends Share 31 Vartika Jain answered this Dear Student, Molality =Number of molesMass of solvent ( in kg)or, Number of moles = Molality×Mass of solvent (in kg) = 9×0.910 =8.19 molNow, Mass of H2SO4=Molar mass of H2SO4×Number of moles = 98×8.19 = 802.62 g% weight of H2SO4= x =Mass of H2SO4Mass of solution=Mass of H2SO4Mass of H2SO4+Mass solvent=0.8020.802+0.910=0.8021.712=46.87Hence, correct answer is (d) 47 View Full Answer
