Question

calculate the maniculas weight and equlent weight a)H2SO4​

Answer 1

Answer:

98% aqueous H2SO4 solution by mass contains 98g of H2SO4 and 2g of water.

Thus in 98% aqueous H2SO4 solution, we have 1 mol of H2SO4, 0.11 mol of water and 1.11 mol of solution (total no. of moles of both the solutes). Calculation follows.

no. of moles of H2SO4 = (989) (98g/mol) = 1 mol,

no. of moles of H2O = (2g/18g/mol) = 0.11 mol.

Thus mole fraction of H2SO4 is 0.9.
