Calculated the mass urea (H_2NCONH_2)required to dissolved in 2.5 kg o – InterviewSolution

1.	Calculated the mass urea (H_2NCONH_2)required to dissolved in 2.5 kg of water to form a 0.25 molal aqueous solution.
Answer» Solution :Molar mass of urea = `60G mol^(-1)` Molality (m) =(mass of urea)/(Molar mass of urea xxMass of WATER in kg) `THEREFORE` Mass of urea = (Molalityxx Molar lass of urea xxMass of water in kg) = `0.25xx 60 XX 2.5 =37.5g`
