K f for water is 1.86 K kg mol –1 . If your automobile radiator holds 1.0 kg of water, how may grams of ethylene glycol (C 2 H 6 O 2 ) must you add to get the freezing point of the solution lowered to –2.8ºC?
Text Solution
Verified by ExpertsThe correct answer is:
B
T f = i × k f × m
2.8 = 1 × 1.86 × 
x = 
= 93 g
