Problem

Twenty cubic centimeters each of ethyl alcohol (

\text{C}_2\text{H}_5\text{OH}

; density

= 0.79

g/cm

^3

), methyl alcohol (

\text{CH}_3\text{OH}

; density

= 0.81

g/cm

^3

), and water (

\text{H}_2\text{O}

; density

= 1

g/cm

^3

) are mixed together. What are the mole numbers and mole fractions of the three components of the system?
