A 5% by mass of an aqueous solution of A of molar mass 342"gmol"^(-1) is isotonic with 0.878% by mass of an aqueous solution of another substance B. The molar mass of B in "gmol"^(-1) is
A solution of 17.1 w% of sucrose ( molar mass = 342 " g mol"^(-1) ) is isotonic with a x w% solution of oxalic acid ( molar mass = 90g " mol"^(-1) ). Assume the degree of dissociation of oxalic acid as 0.01. What is x ?
A 5% solution of cane suger is isotonic with 0.5% of X. The molecular weight of substance X is
A solution containing 10 g per "dm"^3 of urea (molar mass = 60) is isotonic with a 5% (mass by vol.) solution of a non-volatile solute. The molar mass (in g "mol"^(-1) ) of non-volatile solute is
A 20% (W/W) solution of NaOH is 5 M. The dens of the solution is
A 5.25% solutions of a substance is isotonic with 1.5% solution of urea in the same solvent. If the densities of both the solutions are assumed to be equal to lg cm the molar mass of the substance will be
The molar mass of a solute X in g mol^(-1) , if its 1% solution is isotonic with a 5% solution of cane sugar (molar mass = 342 g mol^(-) ), is
100 mL of 1.5% (w/v) solution of urea is found to have an osmotic pressure of 6.0 atm and 100 mL of 3.42% (w/v) solution of cane sugar is found to have an osmotic pressure of 2.4 atm. If the two solution are mixed the osmotic pressure of the resulting solution in atm is Assume that there is no reaction between urea and cane sugar )
