How many grams of ethanol (density 0.80 g/cm 3) should be added to 5.0 g of chloroform (density 1.5 g/cm 3) if the resulting mix
kaheart [24]

Answer:

9.2 grams of ethanol should be added.

Explanation:

Let the mass of ethanol be x

Density of an ethanol = d_1=0.80 g/cm^3

Volume of the ethanol =V_1=\frac{x}{0.80 g/cm^3}

Mass of chloroform = 5.0 g

Density of an chloroform= d_2=1.5 g/cm^3

Volume of the ethanol =V_2=\frac{5.0 g}{1.5 g/cm^3}=\frac{1}{3}

Mass of the mixture,m  = x + 5.0 g

Density  of the mixture = d=1.2 g/cm^3

Volume of the mixture=V=\frac{m}{1.2 g/cm^3}=\frac{x+5.0 g}{1.2 g/cm^3}

V=V_1+V_2

\frac{x+5.0 g}{1.2 g/cm^3}=V_1+\frac{1}{3}

\frac{x+5.0 g}{1.2 g/cm^3}=\frac{x}{0.80 g/cm^3}+\frac{1}{3}

Solving for x , we get

x = 9.2 g

9.2 grams of ethanol should be added.
