Question

A 44% wt/wt solution of H2SO4 has a density of 1.343g/ml. What mass of H2SO4 is 60ml of this solution?

Answer 1

thanks nicely ,hope this will help you .

Wsolute = mol x molar muss molnity means 'n mole Present in 1 L (looomla Solution Given 44% Wt/wt of H₂SO4 density 1.343 g/ml mass of HaSO4 = 44 gram {44% means 44g H21.04 in 100g Solution mass of H₂O = 54 gram mass of solution = 100 gram to Calculate the AUSS volume of solution density = volume volume = 74.46 me 1.343 to calculate mass of Hasoy in 60 ml Molarity Wsolute / Msolute vin L 44 90 0.448 74.46/1000 = 0.07446 = 6.016 M Now 6.016 mol H2504 (589.560 gram) Present in - IL 21000 ml) 1589.560 gram Haso 4 in = 10oome 1 me Contain = 589.568 1000 60ml Contein - 589.568 fර එ = 35.37 gram
