5.0 moles dm3
3.0 moles dm3
2.5 moles dm3
1.0 molesv
0.5 moles dm3
Correct answer is C
Molar mass of KCIO3 = 122.5 g/mol
3.06g = 10
xg = 1000
frac3.06∗100010
= 306g
Molar conc = fracMassconcMolarmass
Molar conc = frac306122.5
= 2.497mol/dm3

Fractional distillation without a dehydrant
simple distillation with a dehydrant
fractional distillation with a dehydrant
column chromatography
evaporation
Correct answer is C
Fractional distillation with a dehydrant is the most likely separation process to yield high-quality ethanol from palm wine. Adding a dehydrant helps to remove water from the ethanol more effectively during the distillation process, resulting in a higher purity of ethanol. This is important for producing high-quality ethanol suitable for various applications, including consumption or industrial use.
