Answer to Question #127573 in General Chemistry for Wila Putra

Question

how much temperature does it take to boil 17 grams of ammonia in 500 grams of water

Answer 1

Moles of NH₃ = 17 / 17 = 1 mole .

Molality = moles / mass of solvent in kg .

Molality = 1 mol . / 0.5 kg .= 2 mol /kg . = m .

elevation in boilling point = (K_b ) * m ;

elevation in boilling point = ( 0.512 ) * 2 = 1.024 k .

boilling point of solution = ( 373 + 1.024 ) k .

So , boilling point of solution = 101.024 k . Answer .
