Answer to Question #145074 in Inorganic Chemistry for merima hamzic

Question

What is the boiling point temperature of a solution of 0.66moles of Mg(OH)2 in 1,000 grams of water? [1mole of total ions increases the boiling point temperature of 1 kilogram of water by 0.51°C.](Show calculations) = ______ °C

Answer 1

ΔT= Kb.m.i. Kb = 0.51. m= molality=0.66moles/1Kg i= 3

ΔT = 0.51 × 0.66 × 3

ΔT = 1.0098°C

ΔT = T_solution - T_water

T_solution = T_water + ΔT

T_solution= 100°C + 1.0098°C

= 101.0098°C
