Answer:
Check the explanation
Explanation:
colligative property
a. let the salt in question is NaCl
to raise temperature of water from 95 to 100 oC
dTb = 100-95 = 5 oC
use,
dTb = iKbm = 5 oC
= 2 x 0.512 x grams NaCl/58.44 x 3.8
grams of NaCl salt needed = 1084.33 g
b. with,
1 cup = 273 g
thus,
amount of salt NaCl = 1084.33 g/273 = 3.97 cups (or 4 cups)
c. Yes, to raise the temperature of water by 5 oC the amount of salt needed for 3.8 kg water is reasonable.
