what is the minimum mass of ethylene glycol that must be dissolved in 14.5 kg of water to prevent the solution from freexing at

lbvjy [14]

Answer:

The minimum mass of ethylene glycol = 6.641 Kg

Explanation:

$\Delta T_f= T_f-T_f'\\T_f'=T_f-\Delta T_f$

Where T_f = freezing point of pure solvent water, 0°C

T_f'= Freezing point of solvent after mixture

K_f = Freezing point depression constant = 1.86 °C/m

Moecular weight of ethylene glycol = 60 g/mol

Weight of ethylene glycol = 14.5 Kg= 14.5×10^3 g

molality of ethylene glycol

$m = \frac{weight}{mol.wt} \times\frac{1000}{V}$

Substitute the values to calculate m

$m = \frac{w}{60} \times\frac{1000}{14.5\times1000}$

by formula

$0-(-14.2) =1.86\frac{w}{60} \times\frac{1000}{14.5\times1000}$

calculating we get w = 6641.93 g

Therefore, The minimum mass of ethylene glycol = 6.641 Kg

Water is intitally present in a state where its molecules are far apart. During a change of state it’s molecule slow down which

Tresset [83]

Molecules will move faster and spread apart on warmer temperatures The colder it get the slower the molecules move so naturally those water molecules are on the path to freezing
