Calculate the mass of urea `(NH_(2)CONH_(2))` required in making `2.5 kg `of `0.25 `molal aqueous solution.

Calculate the mass of urea ("NH"_(2)"CONH"_(2)) required in making 2.5 kg of 0.25 molar aqueous solution. We know that molarity (m) =("Moles of solute")/("Mass of solvent in kg") and moles of soute =("Mass of solute")/("Molar mass of solute") So, find the molar mass of solute by adding atomic masses of different element present in it and mass by using the formula, Molality =("Mass of solute/molar mass of solute")/("Mass of solvent in kg")
